Tekken movement is like Marvel movement. It's clunky and hard when you first get into it but when you learn to cancel dashes into each other it starts to feel great.
In both of those games you can tell good players from great by how they move.
The emphasis on good movement is a big reason why I stuck with Gundam for so many years (and why I always liked Virtual On).
Yeah, you could do combos and shit with melee, but for the most part, the big thing in that game is learning how to move and dodge effectively. You could move in a manner that keeps you at max lock-on range, or you could try to move in a fashion that gets you prime for melee (it's usually a combination of both). It made the neutral game a lot more exciting for me.
