This is amazing.

I can't believe how stunning some of these level's look on what seems to be very little processing. If the "Statistic's" panel is right for example, the entire Shadow Temple in Ocarina of Time 3D is being rendered in just 29 draw calls and 8104 triangles and honestly it looks better than half the games that come out today.

I feel like level design isn't quite as clever as it used to be.

I mean, I'm cheating a bit. These levels don't have any of the actors or interactive elements per-room. The lighting and animations are probably the biggest thing that contributes to the "stunning" quality -- try turning off vertex colors in the Render Hacks panel.
