What console version would you buy FFXIII on? and why would you do it?

Same as DragonHeart: I would buy it for the PS3 because I own a PS3 and not a 360. I never really saw a reason to go buy a 360, even though there are some games that I would like to play on it, it's still not really enough for me to go get one.

What benefits would you get from buying the version you choose?

Hmmm... I guess again, I would have to go with what DragonHeart says and that's actually being able to play the game. I can't think of any real differences that the two may have, except that the 360 version will have to have multiple disks to handle the whole game. So I guess a benefit would be that I don't have to get up and change disks when prompted to do so.
