Such an architecture is typically shit. Building a system that is simple AND scales high won’t work. Complexity usually gets added to cope with scale. If we don’t allow companies to build scalable (i.e. complex) systems, we simply won’t get such games anymore.

Again: I am completely in favor of forcing devs to release everything necessary to host it. I am not in favor of forcing devs to target home machines for their servers, when their servers clearly have completely different requirements. That’s unrealistic.
