Well, that's one way. Back in the old days, many game designs were 
actually based on that kind of restrictions, simply becaues it 
wouldn't have been possible to implement the games at all otherwise.

The whole idea of tiled 2D graphics is one such restriction, for 
example. Until around ten years ago, 3D graphics in games basically 
meant flat colored filled polygons at best, as shading, texturing and 
that sort of stuff was just not possible to do in real time on any 
widely available hardware.
