Innovative and underrated
Not only was it in full 3D, unlike Tekken's previous `on rails` 3D technique, but it also awarded you for being a skilled gamer.
The majority of 2D and 3D fighting games allow most gamers to reach the end of the game by doing nothing more than a couple of powerful/unblockable strikes that will easily defeat your opponent. To fully complete Wu-Tang, and defeat all your enemies, you had to master every ounce of fighting technique that your fighter had, this included blocking, throws, counters, and 5+ hit multi combos.
This game is a rare and surprising treat that deserves more respect than it is given.
