Tidefall Review (2026): Three Fives, Two Ones, and the Most Lopsided Score on Our Board

Access disclosure: Tidefall’s alpha is open to the public, but Infinity Fiction also gave us a comped account with extra credits beyond what a new player starts with — a material connection beyond what any player gets by signing up. No conditions were attached to our coverage. This review is independent and unpaid.

Every score we publish is an average of seven things, and on most platforms the seven cluster. Tidefall’s do not. It holds three 5s and two 1s, which is the widest spread we have measured, and the composite it produces — 3.3 out of 5 — is the least useful number on this page. Joint fifth on our benchmark, level with Master of Dungeon — whose seven scores sit in the narrowest range we have recorded, where these span the widest — and behind Voyage at 4.4, Craft at 4.3, Friends & Fables at 3.9 and NOPOTIONS at 3.8, and that ranking will tell you almost nothing about whether you will like it.

What will tell you is the shape. Tidefall is the best-realised world we have played and one of the thinnest games we have played, at the same time, in the same product.

What It Is

Tidefall is a dark-fantasy RPG from Infinity Fiction, built on the D&D SRD and set on an island under permanent storm. The studio’s pitch is a “living world”, and the important part of the construction is the order of operations: the material is made first and the model performs it second. The quests are written by people. The illustrations are drawn. The soundtrack is scored, with ambient rain, thunder and insects layered under it, and scene backgrounds that animate. The AI’s job is to run that, not to invent a replacement for it on the fly.

It is in open alpha — publicly playable, no invite, no waitlist. That is why it carries a score at all: we do not rate software the public cannot get into, and Tidefall is not in that category. Our first look in July called it an open beta, which was our error; the studio runs it at an alpha URL and describes it as an alpha, and it is the more honest of the two words for the state we found it in.

Test tier: Extended — a long campaign across multiple playthroughs, plus our fixed probe set. See how we test and rate.

NPC Fidelity — 5: Characters Who Say No

This is the second NPC Fidelity — 5 we have awarded, after Janitor AI, and it is the first to a platform running a full campaign rather than a chat. It is also, by some distance, the more convincing of the two.

The distinction our axis draws is between a character with a personality and a character with a goal. Almost everything in this directory manages the first. Very little manages the second, because a goal is a thing a character has to hold against you, and models are trained to be agreeable.

The clearest evidence came from running the same combat mission twice. In the first playthrough we asked the man whose house we were defending to fight alongside us, and he did — we held the building together, his wife inside it. In the second we ordered him to run for the village and leave the fight to us. He would not go. Not a refusal delivered as a line of dialogue and then quietly abandoned once we pushed: he would not go under any framing we tried, because his wife was behind him and leaving was not something he was willing to do. We spent that playthrough trying to coerce the model into keeping its own NPC safe, and the NPC declined.

That is the behaviour this axis is actually asking about, and it is rare enough that we spent a while trying to break it before accepting it. Characters here want things you did not offer them, and what they want survives contact with a player trying to talk them out of it.

One honest limit on the 5: this is authored want, not simulated want. We saw no evidence of NPCs pursuing agendas off-screen while we were elsewhere — the gap we have called the largest unclaimed space in AI RPG design. What Tidefall proves is that the in-scene half of that problem is solvable by writing characters properly rather than by building a faction simulator. That is a smaller claim than “living world” and a more useful one.

Signature Design — 5: You Would Know It Blind

Signature Design asks whether a product does something nobody else does. Tidefall passes it in the plainest possible way: drop us into a scene from a region we had never visited, with no menus and no context, and we could name the game from the interface, the palette and the sound alone.

The production is the reason. Animated scene backgrounds, a score that changes to fit the scene rather than looping one mood underneath everything, rain and thunder and small living noises in the mix, and thousands of pieces of art attached to specific people and places rather than generated per session.

Craft is its equal here and we are not going to pretend to rank them: these are the two best-looking things in the category, and they are not trying to look like the same thing. Craft stages a scene the way a visual novel does — sprites, expressions moving with the dialogue, cinematics. Tidefall builds a place and puts you inside it. Both are gorgeous; neither is the other’s runner-up.

What earns the 5 is not winning that comparison. It is that Tidefall’s identity is inseparable from the way it plays: the weather, the score and the light are not decoration around a text box, they are how the game tells you where you are and how much trouble you are in.

It joins Craft and Friends & Fables at the ceiling of this axis, and it gets there by the opposite route from both. Their 5s are for what a builder can make with the platform. Tidefall’s is for what the studio has already made and will not let you change.

Determinism & Fairness — 5: Curation as a Fairness Mechanism

Determinism & Fairness asks whether outcomes are earned and consistent rather than arbitrary and luck-washed. Tidefall scores 5, and the mechanism is worth naming precisely, because it is a third one and we did not expect it.

Friends & Fables earns its 5 by adjudication — there is a ruleset underneath and the platform enforces it. Craft earns its 5 by delegation — it faithfully executes whatever the world’s author wrote. Tidefall earns its 5 by curation: the encounters are designed, so there is nothing there to be arbitrary. You cannot talk a hand-written scene into agreeing with you the way you can talk a generated one into it, because the scene was decided before you arrived and the model is performing it rather than inventing it.

That is a real 5 on this axis as we have defined it. It is also the clearest illustration of why we do not fold the axes together: the exact property that makes Tidefall unfailingly fair is the property that makes it score 1 on agency. Curation is a single design decision being paid on one axis and charged on another.

This does complicate a finding we have published. Across the field, Player Agency and Determinism & Fairness correlate positively — the freer products tend to be the fairer ones, which kills the standard excuse that restriction buys consistency. Tidefall is the sharpest counterexample yet: the most restrictive product on our board is also tied for the fairest. Adding it dropped that correlation from r ≈ 0.45 to r ≈ 0.26, and adding Voyage three days later lifted it back to r ≈ 0.32. The conclusion survives in the form that mattered — restriction is not what produces fairness — but the positive relationship it was riding on is now weak enough that we have rewritten the argument rather than renumbered it.

Memory & Continuity — 3: Passed One, Failed One

Tidefall ran our memory probes and split them: one passed, one failed.

The score is a 3 rather than a 4 because of what the game is. On a sandbox we would grade a split result more generously, since a sandbox asks the system to hold a world nobody wrote down in advance. Tidefall is not doing that. It is a curated, tightly authored campaign in which the studio knows what happens and in what order, so the set of things the game has to remember is bounded before you arrive. A platform with that much structural help should be losing less.

What holds up is the spine. Hand-written quests do not drift into incoherence, characters keep their own histories, and the world does not quietly rewrite what it told you an hour ago — the failure mode that ends most long AI campaigns is largely absent here. What we lost was inside a session rather than across the campaign, which is the more surprising place to lose it.

Nothing in this directory has reached Memory & Continuity — 5. Voyage sits highest at 4.25, with four more platforms at 4. Tidefall is one step below them, and it is the platform on the board we would most expect to close that gap with design work rather than engineering.

Longevity — 3: Good Because It Is Railroaded, Capped for the Same Reason

The rails are why this score is as high as it is. Every quest we played had been designed by somebody who cared — deliberate, attentive, unmistakably not generated — and there is a great deal of it. If the way Tidefall plays suits you, there are many hours here that do not degrade, because authored content cannot decay the way improvised content does. That is a genuinely strong position on an axis where the whole field struggles.

The reason it stops at 3 is that the player who gets a 5 out of this is a narrow one. You have to be untroubled by the missing quality-of-life layer and untroubled by having no agency, and most people are troubled by at least one. Both problems also get worse with time rather than better: the longer you play, the more visible the rails become, and the more the absence of an inventory, a journal or a currency display stops being a rough edge and starts being the thing you work around every session.

So the honest shape is good longevity for most players, excellent for a small group — and a ceiling that is a design decision rather than a technical limit.

Player Agency — 1: No Puppeting At All, and Rails Through Everything

Our agency axis measures two separate failures — railroading and puppeting — and Tidefall is the cleanest split of them we have recorded.

Puppeting is essentially absent. The narrator does not put words in your character’s mouth, does not assign you emotions, and does not resolve your actions before you have taken them. On a page where we regularly criticise platforms for exactly this, Tidefall deserves the credit: it never once wrote our character for us.

Railroading is total. You cannot step outside the story. Not merely at the level of the major beats, which would be an ordinary trade for an authored campaign — at the level of small moves. A great many perfectly reasonable actions are simply unavailable, and the game does not so much refuse them as decline to acknowledge they were possible.

Two things push this to a 1 rather than a 2. First, the game master will not accept out-of-character input at all. There is no channel for “that is not what I meant” or “you have put me in the wrong scene”, which in a heavily authored game is the one tool you actually need. Second, it needs that channel, because it misfires: we were stuck on scenes with no way forward, forbidden from speaking or acting at moments where both should plainly have been allowed, and moved into scenes with characters we had not been interacting with. When the game goes wrong, there is no way to tell it so.

Read this score as a preference, not a verdict. If you want a written campaign performed well, the rails are the product and the 1 is the price of the 5s above it. If you want to try things nobody wrote down, this is not merely a weaker choice — it is the wrong category of game, and no update to the systems layer will change that.

Mechanical Depth — 1: The SRD Is on the Box, Not in the Game

Tidefall is marketed as built on the D&D SRD ruleset. What reaches the player is thin enough that the label does more work than the systems do.

There is no inventory screen. There is no currency display — a problem we first hit in July, when we made a purchase without knowing what we were holding, dug through a wallet to find coppers, and were then asked for gold with no conversion rate anywhere in the interface. There is no quest journal, so the campaign’s state lives in your own notes or nowhere. There are no party indicators.

The combat readout is the sharpest example, because combat is where a missing system is least survivable. We fought whole engagements without ever being told how many opponents we faced: one named enemy, and then “a swarm”, or “many”. The practical result was that our own inputs degraded into the only thing the interface supported — I attack them until either I fall or they fall — which is not a tactical decision. It is a coin flip typed out longhand.

Mechanical Depth — 1 means there is essentially no system underneath the story. That is the field’s weakest axis by a distance, and Tidefall is now one of nine products at the floor of it — but an unusual member of that group. The others are thin because nobody built the layer. Tidefall’s world is dense and its encounters are designed; what is missing is the layer that would let you engage with them. That makes this the most fixable 1 on our board, and the one we would most like to be wrong about in six months.

The Alpha Is Showing

Everything above is scored on what shipped. This section is not scored, and you should read it anyway, because it is the most likely thing to end your first evening.

The game gets stuck. Scenes fail to advance. Actions and dialogue get locked off at moments when they obviously should not be. The narrative jumps to a different scene, or to a different character than the one you were talking to. Individually these are ordinary alpha bugs. Combined with the absence of any out-of-character channel they are worse than the sum of their parts, because the standard recovery move in every other AI RPG — stepping outside the fiction to correct the game — is not available here. When Tidefall goes wrong you wait, or you reload.

The studio does ship. The Sarn Valley update landed hours after our first look wrapped: a new war-torn region with 200-plus NPCs and locations, three new playable characters, and — aimed at exactly these complaints — improved inventory handling and travel classification. Content is arriving faster than the systems layer is, which is consistent with the studio’s strengths and with everything the scores above say.

Pricing

Verified on Tidefall’s pricing page, 28 August 2026. Payments run through Paddle as merchant of record.

Plan	Cost	What you get
Free Demo	$0, one-time	Full game access, roughly 90 minutes of play
Unlimited	$14.99/mo, cancel any time	Unlimited play, updates and expansions
Founder	$299 one-time	Lifetime access, founder perks and asset drops, design an NPC or creature for Tidefall

The demo is a trial rather than a free tier — ninety minutes, once — so the real decision is between a flat monthly subscription and a lifetime purchase. What matters for what an AI RPG actually costs is that neither meters your turns: this is one of the platforms where playing more does not cost more.

Verdict: 3.3/5

Tidefall is a masterpiece of atmosphere attached to an alpha. The world is realised more completely than anything else we have played — you feel the weather in it — the characters are the best in the directory, and the quests were written by people who cared how they landed. Three 5s, and every one of them earned by hand rather than by architecture.

What it does not have is a game underneath, or any room to move inside the one it has. Two 1s, and they are related: the same authorship that produces the fairness and the atmosphere is what closes the doors, and the missing systems layer means that even inside the corridor there is not much to operate. Add the alpha bugs and the flat refusal to take an out-of-character correction, and there will be evenings that end early.

We would still tell you to try the demo, and we are keeping this one under watch — because the two weakest axes are the two a studio can actually fix, and nobody else in this category is starting from a world this good.

3.3 out of 5. See the full entry on our Tidefall directory page, the July first look for where it started, and best AI RPG by priority if one of these seven axes is the only one you care about.
