There's actually three distinct versions of this game (or more accurately, three completely different games that share the same name):

-PS3/Xbox 360 version (which this leaderboard covers)
-Wii/3DS version
-DS version

Since these three versions are fundamentally different games, they should be treated as such. As a result, this leaderboard will remain exclusively for the PS3/Xbox 360 version. If you wish to have a leaderboard for one of the other versions, you should request it as a separate game here:
