Ok, I appreciate Beat Em Up's are short but this is way too short. You can unlock most characters in 20 minutes.
More importantly, the game is imbalanced compared to its predecessors. I find it impossible to 'juggle', you can't 'counter a counter' and the combat system seems poor.
I tried learning some characters but it's rather pointless as button bashing is all too easy. At least in Tekken the blocking system makes it more difficult for button bashers to win.
The graphics and sets are outstanding. However, I was disappointed with this game. I'd maybe recommend renting if you have some mates round. But don't expect to learn a character and kick ass, because its pointless.
I'd rather play Tekken 3, at least you can do decent 10 hit combo's and spend a bit longer unlocking the characters.
If your girlfriend doesn't really play games but you want her to feel like she can, then buy this game as she'll probably kick your ass.
