Interesting..

Yes.. I can see that the game action (at a high level) is not particularly
computationally intensive.  After all, you're basically responding to
keystrokes, and those are probably 10s if not 100s of milliseconds apart.

The challenge is in having fast loading of large image databases to pull
from and render.  The engine, I'm sure, does the texture mapping onto
surfaces  and it does the 3d geometry calculations.  But something has to
say "here's the set of polygons/surfaces to render, here's the textures to
map", and go fetch those.
