Lol Tekken's never been my fav fighting game, but I can't knock it either. Soul Caliber had Darth Vader...Spawn... It was probably a marketing move... He kind of fits in it seems when I think about it though...idk.
Well it's not a contest it's just a day, and I don't have an ugly christmas sweater so you got me beat.
They didn't say anything about one being mandatory so... no.
