Back in May Big Ant made the decision that releasing a broken game (and lets not kid ourselves, what was released in May was an absolute disgrace) on PlayStation and PC was a better option than delaying the game so that it could be released with all promised features (like Pro Team) on all three platforms, including Xbox, in a playable state.
In making that decision, Big Ant blew up their relationship with Microsoft.
Blaming Microsoft for anything is ridiculous. It was Big Ant who made that call back in May, and we now all have to live with it. But without an Xbox version. Or Pro Team. Or Hamish. Or … You get the idea.
