No sucessfull 3D?
.. because its cheaper to just make the same 2D game again and again and again with minor cosmetic changes, the same "story" with a different name on the bad guy with some sort of dumb world-shattering goal, some extra pokemon, and -maybe- some significant change/improvement to gameplay. Nearly no development cost, same price tag at the end.
And people buy the games as if they were the new hot stuff everytime = profit.
