Here's a dream game idea that I have... It would have the gameplay of Doom or Duke3D, where you run around in a polygonal environment and shoot at sprites. Except... those sprites would all be created from live-actors that were standing in front of a green screen, much like the original Mortal Kombat.

Thoughts, people?

I'm going to bet that some terrible game like that was already made in the 90's.

Sounds like what Vinny was suggesting as the new DOOM in the latest bombcast.
