If I were an NPC in an RPG, I'd probably ruin the game, because once the player talked to me, it'd irreversibly result in them being bottled, geniefied, and given a game over as a result.
... Wait, that would just make me a Sierra Adventure Game NPC.
@Phorm Or a furry porn RPG.
@Doephin Furry porn ARPG.
Like Diablo, only you bottle your enemies. And obsess over your stats (which correspond to your measurements) and your skill tree.
I'm gonna main AOE geniefication, obviously. But there's a strong argument to be made for the hypnosis branch.
