it seems the topic here has shifted, but nonetheless, my favorite thing about machines is the fps/rts capability, even if it is limited fps. The only other game like that I know is Battleswarm: field of Honor. It's a free multiplayer game with fps players against rts. The rts is kinda messed up to make it fair, though. Anyway, the machines fps made you capable of having smarter troops to balance for the fact that the cpu could make instantaneous decisions when you had to put the building in just the right place, taking much longer.
