Yep, no multiplayer on any version except the Wii. It was stupid reasoning for not putting it on 360/PS3, they said
something like it was to make up for what the Wii lacks compared to the other versions (graphics, physics, etc).
And yeah, this is exactly like a GotY edition which normally include all the DLC like this does, except TFU didn't win any GotYs so they had to call it something else.
Hopefully people can at least create new models and skins for the game, if not more. We'll see if anyone is interested enough to even try.
