Tekken has flanderized its gameplay into being all about the aspects that came to un-intentionally define it post Tekken Tag Tournament.

You ever notice how Tekken 2-3 have almost zero interest from Tekken players? There is no Super Turbo of Tekken. No 3S. Even TTT barely gets any attention. It's because those games have almost nothing mechanically in common with the new games. Even less than SF6 has to do with the 2d era SF games.
