Tekken, and Tekken 2 were both done on System 11 hardware, same as what is in the PlayStation. Tekken
3 was the first title released using System 12. This is a faster system with more memory,
making a faithful PlayStation conversion impossible. Certain things has been sacrificed, thus the polygon count is slightly reduced. It plays the same, but does not look "quite" as good as in the arcade. A new character, is included, in true Namco fashion. A most excellent game, must buy for sure!
