It's still don't get mo' better than Tekken, baby!!
Sure it's 6 years old, but who care. The gameplay is as solid as it's ever been. The sound is what you'd expect from Tekken. There's a lot of replay value, include with the awkward-but-fun Tekken Bowl mode. The only real problem I had was that the endings weren't in CG, but in the gameplay graphics. Fortunately, that's not a big problem.
Tekken fans, you may be hell-press to find the game today. I was lucky to have it as my first Playstation 2 game. But if you do find it, I have no doubt that you'll enjoy it. Not the best in the series (that Tekken 5), but very close to perfection.
