Usually people that hate on Tekken don't "get" the series, you can't play it like other fighters. It's all about comboing and taking control of a match, it's a very offensive focused game. That's what's so great about the series, Tekken 6 just refines it again, which is a good thing since the last time they tired to stray too far from the formula we got the shitty Tekken 4. Hell, just adding the rage system in T6 can completely change the way a match plays out, makes for very exciting comebacks.
Tekken is the #1 fighting game in Japan for a reason. Sure, you can play it like normal fighters with your friends and I can see how it would be boring, but if you take time to learn the game it's very exiting. The game runs at 60FPS with a lot of shit going on, the models look great in motion.
