I have no problem if it goes multiplatform - I intend on purchasing a PS3 and already have an Xbox360, but still, I wouldn't have a problem. I encourage this end of things these days as it means that more people are able to play more games. and that's a good thing.
As for the debate over whether or not FFXIII Versus is gonna be anything great or not - All I care about is this: "[Nomura] has also stated that the development team have been implementing a traversable world map, used in the main Final Fantasy series up until its removal in Final Fantasy X"
That may sound like a silly reason to buy a game, but this is about 99% of the reason that I want to buy this game. Really. I just like to make little FF characters move around little spheres. This is how I define joy.
