I mentioned the "differences" thing because of what Zero said about it.
What it's available on should not matter. For example, the snes version of Justice league Task Force is COMPLETELY different the the Sega Genesis version as they have a different set of moves and sprites for each respective system. The sounds are different, the moves are also different. They may contain the same characters, but all of the sprites are different.
You don't have to post the differences between the versions of the games in this concept. You can if you want to but it wouldn't be required if you were just reviewing the one version you have. Basically, if you have the 360 version just worry about that version.
