I honestly cannot see why people are complaining about Tekken 4\'s graphics. The texture work is pretty good for PS2, and the characters are very detailed and are animated very well. The stages are also nice lookin\'...
I guess those screenshots/movies of DOA3 kind of spoiled \'em.
If there were any improvements to be made... Well, really considering the hardware this game is running on, it looks fine. The improvements that I\'d want(Higher polygon counts for the characters/arenas, better textures(They\'re good, but they still look bland like most other PS2 games)) would be pretty hard to do.
