My g/f has picked up on Black and White, which is in every way I can think of an awesome game, if a bit hard to get all the basics down.
If you've never played it, get a copy. You will thank me once you get a handle on the controls and mechanics.
She likes this game a little too much though, I think. The other day, she was teaching her creature Lightning Blast by shooting random villagers and buildings (her own, mind you), and I've never heard her cackle with such glee as when the creature dinged 100% learned, and proceeded to make its mother proud by blasting about 6-7 children that were standing nearby.
This woman desires to be a school teacher, btw....
