I think this is basically the responsibility of the parent developer. It would take a very high level of Project Lead knowledge and understanding to manage it, and you would actually build out your own architecture to develop multiple games, and you'd have to have very good knowledge documentation on them; but I think that's the better way to build games in the future.

I just don't know that anyone actually does that yet. Frankly, because I think they're all coders and they're not thinking about managing a framework as your own platform to build different games thorough.
