I have the PS2 version and it's great. I'm only interested in the manager mode and made a team called "Crawley Town" and we made it the the 4th round of the league cup, lost against Crewe 17-16 on penilties in the first round of the Johnstone Paint and funnily enough met Brighton in the final of the FA cup and beat them 3-1. And won the league two with 125 points and without a loss.
Hang on...
On World Class, you -
* Won League 2 with 125 points without a loss
* Got knocked out the league cup in the 4th round
* Got knocked out the paint pot in the 1st round
* and beat BRIGHTON in the FA Cup FINAL?
Can you see why people don't believe you? How would Brighton get to the FA Cup final on World Class? And you go the season without losing a game, and then lose 9-2? Not even close?
Iffy.
Perhaps the PS2 version is just shit, and unrealistic compared to the PS3 version.
