Imagine a game that looks as good (or better) as any game currently on the market, in nintey-six KB.

This is insane.

If you're not running at least a GF4, you'll run into some funky problems with the shaders.

It looks nice, but it runs extremely slow, like com_maxfps 2 slow.

...and there was a clipping problem, and I couldn't move to a different room. =[

As someone who works with prim-based modelling due to its file size, those spiders stuck out to me right away as something created from mathematical primitive geometric shapes, with a few booleans applied.  The textures on these 96k demos have always looked pretty procedural to me as well, something you could create with a formula.

I think you'd be hard-pressed to create a conventional model (say a player model) with this technique.  It's still highly impressive, though.

(Note that I last saw this game a week ago, so if you turn around and point out something I missed... that's because I missed it.)  ;^)

Not knocking it at all,  trust me.  Just trying to counter the "why can't games be made like this, games are bloatware" argument.  (EDIT: Which no one explicitly made, btw.)
