Sure. You wouldn't use pure erlang for a game where perf is critical, but not every game is like that. I bet you could even write a fantastic AAA game by care

Sure. You wouldn't use pure erlang for a game where perf is critical, but not every game is like that. I bet you could even write a fantastic AAA game by carefully dropping into NIFs as necessary. I think though my argument is that you also wouldn't use objects for that sort of thing either. The brittleness of the code has nothing to do with the underlying vm, or its performance, or even it's concurrency, and everything to do with the code architecture and data organization, which is isomorphic between genservers and objects.
