"The key is to unhinge the gameplay thread from the render/physics threads."

Many simple games don't need it, by the way. A lot of 2D indie games don't do complex enough rendering/physics to warrant a separate thread. This, in turn, makes everything much simpler if your entire game only uses one thread.

2D games can be made with anything. 3D action MMOs on the other hand need attention.

Indeed. I have no credentials to speak about such hard problems, my experience is working with high QPS servers written in Lua and a bunch of small indie games. :)
