That's a terrific write-up. I've been a Tekken fan since the second game, and I think this one's the highlight of the series in terms of its roster and depth. I'd like to see the story/endings fleshed out a little more, but they're certainly not terrible. I guess you can't expect much story from what is essentially a side-game to the story anyways.
I've been playing Tekken a long, long time and still regularly get my ass handed to me on a regular basis online. That said, it was one of the friendlier online communities I've seen, with a lot of "GG" messages sent after matches. The community has obviously shrunk, given the amount of time that's passed since the game's release, but it still occasionally has a few players online.
