Games Like Someone Else's War: An Isekai RPG

The AI writes everything except the rules

Every person you meet, every word they say, every errand they hand you and every place it sends you is written by AI while you play. There are no dialogue trees and no script waiting for you to find it. The one thing the AI doesn't write is the rules: turn order, damage and death are hand-made and the same every time, so this is still a game you can learn.

Say anything. They answer what you said.

There are no dialogue options. Lie, threaten, over-promise, confess — you type it, the reply is written for what you actually said, and what you said is what the world then has to deal with. From one playthrough, unedited:

The world is written before you take your first step in it

Every run opens by writing its own world: the age, how magic works, the peoples and what they want, what the Demon King actually is and where he stands right now — then who you were on Earth, how you got here, and the ability you woke up with. Tell it what kind of world you want, or leave it to chance.

The world is built out of what you do in it

Rules the AI can't bend

You can walk into a fight you cannot win. The AI can talk during a fight, but it never decides one: the numbers follow the same rules every time. You can learn this game, and you can misjudge it.

Two kings, and neither of them is yours

A king pulled you into this world to win his war, and a Demon King waits on the other side of it. Both are new every run, and the one who summoned you is keeping a secret. Fight for either of them. Slay the Demon King or turn him to your side; beat the king who summoned you and he yields his crown, alive. Or make a peace both banners will sign. Each one ends the war differently, and the world carries on after it, changed by what you did. Factions keep count of what you have done for them and what you still owe.

Everyone remembers you

You are not from here, and the war did not start with you. Everyone you meet will remember you — not all of it, and not the same way. The AI runs as an online service, so the game needs an internet connection.
