Alright then. Darwinia is a new game being released over Steam. Its probably best described as an RTS, but its fully 3D, and the camera is controlled like in an FPS. You have little creatures called Darwinians, which you indirectly command through officers, which you give instructions to, and who in turn instruct the darwinians.

Engineers look like those things from Tron.
