Basically this game is great. The game seems to have been tweaked and it feels different to Tekken 5, not to mention the new ‘bound’ combo system and the reworking plus extra moves for the old characters. I definitely disagree with the reviewer who said it's the same as Tekken 5 DR.
Anyway, the game is not perfect. The Scenario Campaign is definitely entertaining, and I like the fact that you can do any of your chosen character's moves or even attempt to juggle your enemies. In that respect it's an improvement from Tekken 5's Devil Within game. But the graphics are very average and the story is predictable and extremely weak.
I haven't tried playing online but I hear is terrible at the moment. However a patch is apparently in the works at the time of this review, so we'll see how that works out.
Overall, as far as the 1 on 1 fighting is concerned this game is a big step up and very enjoyable. If you wanted to buy this game for any other aspect, don't get your hopes up.
