I will say this again (since my first post has been quoted many times, by many people).
I don't hate that it went multiplatform. While my jaw hit the floor out of shock while watching the Microsoft conference (why wouldn't I, up to that point it was always a PS3 exclusive, the biggest one). I did not become mad about it hitting the 360.
However I am mad that the game had waited and anticipated for 5 years is not even half the game it was suppose to be. Square had chopped up FFXIII due to game volume and overall balance.
Even if the 360 version had nothing to do with it, when has there been a Final Fantasy game that was toned down because it had to much stuff in it. Entire areas potentially full of characters to interact with or lush vibrant environments to fight epic battles in, were cut from the PS3 creation.
Just to clearify again, I don't hate that it's also on the 360. I'm mad that Final Fantasy XIII isn't even half the game it was suppose to be.
