Oh, thast right. Another good thing for Tekken is that it dosent seem that every character follows the same storyline, in SC, seems like every character follows a yellow brick road, until they have there final Cutscene, which arent great. As Tekken rewards you with a great FMV, while SC gives you a clip with the in game graphics.
Another plus point for Tekken is that in Tekken 5 you can play the arcade versions of Tekken 1-3, what an extra !
