It\'s all opinion, so here is mine.
1: I think the pure speed of a SSBM match , will make it a lot more complex, due to reflexes alone.
2: I think, all around depth, that most likely VF5 would be considered the deepest.
3: I still say Street Fighter 3: Third Strike is the deepest fighting game out there.
4: I\'ve played every Tekken, \'cept for Tekken 5, I just felt the franchise started to go stale. I apperciate what those players were doing, but it was still just downright boring, for me to watch.
