One word : Halo.
PS2 does not have any games that even come close to comparing to 'Halo'. Don't say 'Grand Theft Auto 3 III'. That game is shit compared to the first person shooter that I love to play online with through XBConnect
If you want to own a console that has a great future and is starting to pick up in the games area; buy an XBOX.
