Beatin' all way round might get boring in Tekken eventually. ^^
That's why Tekken 2 had an unique atmosphere. Because of Kazuya and Jun relationship and mysteries around Yoshimitsu and Kunimitsu.
And, I would like to know more, more... MOAR about the Manji Clan, know its members. There were some faces lingering in the background (especially in Tekken 4 artwork), e.g. the big fat guy and a man with thundering swords (reminding me a bit of Raiden from MK), a girl with an umbrella, a guy with big hat and white coat, some masked ninjas... I hope they weren't all killed by Bryan
