The software isnt buggy, my opinion. But i think its not very powerfull. The framerate is very fast down, and nexus is very fast full ^^
I would say its not useable for a commercial-standart-fps. U have to use many tricks to make a working (large) game with good framerate.
But have a look what u pay for other 3d engines... ^^
