A legacy in a Victorian Mansion sounds so cool! Love that you gave us a tip too. I'm always looking to make my builds more authentic. I'd absolutely be down for a haunted legacy playthrough! Btw, got any screenshots? Would love to see how your mansion turned out.

Kids these days with their JSON this, JSON that. XML has been around forever, it's standardized, and it's not going away anytime soon. Plenty of legacy systems rely on it. Try to keep both tools in your belt!
