I think 2d-games are very much underestimated. The choice of the appearance for a game it's a matter of taste, even if the majority only likes 3dimensional games .
I think what ratchet wanted say was that you can achieve the same results using modern technology (which is available anyway) at frame rates hundred times higher (srsly) with much less development effort.
EDIT: Nahh, he probably didn't mean that...
