Do you think games with two dimensional graphics still have a valid place in today's gaming market? In recent years, there have been many many compilations like Sonic's Ultimate Genesis Collection. Entirely new 2D games seem pretty rare to me, though. Even the portable systems, like the Nintendo DS, have moved away from 2D presentations and more toward three dimensional games.
It seems to me like the major game companies now view 2D as something that should be limited to old games being released again or small, quick games like some on WiiWare. I can't think of a single major title upcoming that is 2D.
