lmao the decision to port it to the 360 did not affect the PS3 game at all. If they had decided not to port, they would have probably just released it a year earlier, and the problem with the game cannot be fixed with any amount of polishing. Yes a lot of people like the game as it is, but to the ps3 fans who are dissapointed with it and are using the 360 as a scapegoat, the game would have been just the same whether it was released for the 360 or not. Although I'm sure if the 360 version doesn't sell well, Square Enix will blame it on porting and announce the next version will be exclusive to trick all the gullible people who didn't like this game to buying the next one as well. Personally this will be the last final fantasy I'll buy unless the next one gets good reviews because it was disappointing to me.
As for the prize, I can see why they where booing. They were probably convinced online that the 360 version had made the game worse and so they are frustrated with that. Regardless it is a great prize whether you want to keep it, sell it, or give it as a gift.
