The fighting is lovely, less credibility though. Tekken 4 had more of a strategic thought within it. Tekken 4 you could say was an art, Tekken 5 is more of a ‘I'm going to beat you to a pulp and you can't do anything about it’ sort of duel, except usually they can do something about it and the action is very quick.
The story, woah, it's all so amazingly intertwined. It is like the martial arts world is just one street full of neighbours. The graphics, one word, killer.
Oh and the difficulty, ouch! You begin from Ultra hard because you think just because you beat all the other tekkens with ease, you will smash this one, but soon eonugh you will be beating yourself up and pondering whether it really is a wussy move to play the game on medium or easy level.
Only problem with the game is the huge array of moves to learn, I'd rather not spend hours memorising innumerable moves for each character, and i feel ripped off if I am not a great fighter with every character. So it is a dilemma to either spend many hours perfecting the moves or just stick to my favourites and kick serious butt.
