Don't get me wrong--MGS4 looks awesome. But all you folks who think that Snake is made from 6.4 bazillion polys with no normal mapping or anything are on crack. There are a lot of clever tricks that make that Snake model seem like it has a lot more geometry than it does, including (I'd guess) a lot of normal mapping. If you look closely, you can definitely see the edges in the actual model. Large ones. I've highlighted a few, here:
Before you fire up the flamethrowers, I'm not trying to trash the game or anything. It's visually very impressive, but good 3D design is not just about throwing polys at models.
The hair is pretty sick, though. Anyone know how the PS3's hair rendering system works?
