Pokemon was actually brilliant though! It made having a GameBoy worthwhile!

Well, my favourite game is on PC and 360 (Half Life 2, with Fallout 3 coming an extremely close second). I am guessing that you mean games from the generations before Playstation 2/Xbox/Gamecube, so I'd have to say Tony Hawks Pro Skater 2! That game was awesome, I spent so many hours on it, and it had an amazing soundtrack and the game just never got old. Everyone always says Nintendo games, I was never a big fan of Nintendo back in the day, although Super Mario 64 was real cool.
