I've never been a big fan of the Tekken series, but I must say that I thought Tekken 5 was quite good when I played it. I do enjoy the way that Tekken 5 (I think 3 had one also) puts in a beat em up game in case you get tired of playing the main one-on-one mode.

The fighting isn't as smooth as Soul Calibur 2, but it is still very good.
