Tekken in many ways is more of an in depth fighting game than most fighting games out there in my opinion. Its always focused on the combos and such. Instead of the violence and gore.
Tekken 4 takes away and adds to the Tekken series. The not so great Tekken ball mode is gone. Tekken Force has been upgraded and is slightly harder. There is still survival, training, and practice there also.
Most of the Tekken favorites have returned with a few new characters added. All the characters have voices. The still pictured prologues with a narrator is a good addition. My only small complaint about the game is the music. The music isn't as good in this game as is in past games.
