Heroes Saga

An ordinary guy drops into Valarion and gets mistaken for the Hero everyone summoned. Nobody actually wants a real hero, though — they want a tool, and tools that stop being useful tend to vanish.

He has to fake his way through it, picking who to trust and who to con, since honesty doesn't look like a survival strategy here. Combat runs on turns, letting you plan out fights instead of button-mashing through them, while the rest of the game is spent reading the room, making choices, and getting closer to the women who see something in him worth using or keeping. Scenes with those women unlock as you go and can be replayed afterward through the gallery, so nothing's a one-shot deal.
