Some people live for the thrill of intense, one-on-one fighting. They thrive on the click of arcade stick buttons and sideways glances at the player attempting to steal their thunder. Me, I just want to be a robot kicking a bear wearing a ballerina costume while dodging chickens.
Most of my Tekken memories involve me getting beaten to a pulp by people playing as Eddy Goro, so when I think "fun" there are about three hundred and fifty-seven things that come to mind before Namco Bandai's fighting franchise. I could see Tekken Tag Tournament 2's Fight Lab knocking the series up a few dozen rungs. It's certainly an entertaining way to teach the basics of battle.
My favorite fighting game experience of all time involved some silly game, years ago, that simply ran me through the command list, move-by-move, not letting me progress until I had completed the move on the screen. Every time I get a new fighter the first thing I do is look for such a feature, and if I don't find it I am very disappointed.
This might not be the same thing, but it'll do.
