Does the game actually uses AI for the NPCs? (I'm thinking like those yandere gf escape room games or that one vampire delivery game where you can talk to an AI)
No, like interactive AI that allows you to make choices and say things that the dev. maybe wouldn't have thought of. There was a vampire pizza delivery game, called "suck up," that blew up on twitch like that. Think character.AI made into a actual dating sim game. That was what I was think of.
