Really fun and over the top, but may get old pretty soon...
Pros:
Graphics are really good
Cool Ending for each charecter
Completely forget about Tekken 4
Costumes and a brand new arcade mode
lots of cool moves and great enviroments
no online(so they focus on the one player more)
charecters talk in their native languages
will even appeal to people not into fighting
Cons:
Devil WIthing is just plain bad
Gets old after you beat most of the stuff
Soundtrack is not the best
not too many different enviroments
replaced eddie with christie(totally personal opinion but I'm sure many will agree)
if you like the trailers and gameplay footage of this game, get it. what you see on gamespot does not fool you, it's really that good. just beware it might not last you for too long without playing two player. I myself have already sold it
