So here's the real question. Guilty gear is fundamentally unable to stop making wife guys and then, at the end of their arcs, going "and now go be happy with your wife byeeee"

so once it's done this for every character, it won't have any guys left to wife

Thus it can't be guilty gear anymore. What does it become? A new wife guy based fighting game? A turn based strategy game? Wife Guy racing? I'm unsure
