I own all of them besides the Daxter game. I don't mind Jak 1, but it's not as good as the other games. I like Jak 2 a lot, but Jak 3 is definately my favourite. Jak X is cool too.
Yeah, but I've just got loads of new games for PS2 and only bougt my Gamecube 2 weeks ago. It was cheap too, second hand from my mates brother. £20 ($33) for a Gamecube, controller and 4 games.
