The fundamental problem here is what others have already deftly pointed out. Implementing anything like this in a way that's mature and not purely juvenile titilation of the sort games were and sometimes still are accused of would require such a level of depth and complexity that devs couldn't justify it as a side system. At a certain point it crosses a threshold where if you're going to devote the time and attention to it, you're almost better off using this as the framework for its own seperate game. And I also don't enjoy pretending that this whole topic wasn't started as either bad faith or a dumb, juvenile request at its core.
