It's never really evolving
Tekken 5 is just a overrated fighting game for the Playstation 2 that haven't changed a thing since the third game, except for performance and slightly worked graphics.
And the game haven't ever been really good either, compared to other fighting games for the competetors consoles such as Dead or Alive 3 for the Xbox and the Super Smash Bros. to the GCN, Tekken 4,5 and all other Tekken games for the PS2 doesn't live up to them to any point.
The charathers in the game have a huge variarity of different wierd clothing and strange hairstyles, but some actually looks serious enough to fighting with in the game, and the whole fighting is similar to all the other games, which someone fight find interesting but it's pretty slow and no big variaty of combos or anything like that.
For those who liked the precious games probably likes this becuase it's pretty much the same thing as all previous games.
