All the MK arcade games had digital controls.

Well, the one game I played the most on MAT I was (and still is) Smash TV, and that game gave the choice to use either the analog sticks or the regular controller, or combinations (move with left analog stick, attack with buttons). I'm pretty certain MAT II will let people control it "normally"... and with an arcade stick. If not (which is unlikely), it'll be a HUGE mistake.
