D-Pads have a curve that starts from the center, where it's at its deepest, and gets progressively thicker as you get to the edges of the individual directions. Making it easier for your thumb to switch from one direction to an other. Regular individual buttons simply don't allow for the same kind of smooth transition. |
Using buttons for directions have their own advantages too. Wich is why the Hitbox was so controversial in a certain popular fighting game (you could move forward and block at the same time in MvC3 XD).
