Well, when I was younger I really liked playing Gianna sisters (sp?) on the good old Comodoore 64, or Atari. hehe.
I liked Where in the world is Carmen San Diego too... but I think that if I should have to play them now, I would get bored.
I like platform games, and games that you're not limited to with time.
Sounds morbid, but I really love Grand Theft Auto... the new one, forgot the name. I started playing that when it was on the computer as a birds eye view, little box game.
Its evolved so much, and is definately 100% better. I think I need to invest in a PSP, so I can play to my hearts content. Anyone got one of them?
