"Platform game, or platformer, is a video game genre characterized by jumping to and from suspended platforms or over obstacles. It must be possible to control these jumps and to fall from platforms or miss jumps."
The wife loved Psychonauts and really likes the 'lego star wars/indiana jones' type games, but I don't know what else to grab for her.
I did this exact same thread for PC games and got one or two really good suggestions out of it so if you guys can suggest some games like Psychonauts for the 360 I'd really appreciate it.
