Alright, here is the story. My sister gets addicted easily to game (she played Portal for 2 months, and only in the story mode, no custom maps), and she has already played Psychonauts for 6 months. And I'm getting tired of it. Now, I need a game to stop her annoying me with it, so I need a game similar to it at least in the ages meant for it. Oh, and it's for PC BTW, we don't own consoles.
Games she has played:
Psychonauts
Portal
Grim Fandango
Crayon Physics Deluxe
