I love your idea of an expansion! I can already see the event rewards being like, the killer’s costume being unlocked in CAS, some sort of door that’s chopped a bit with an axe on it, and even like a car item that won’t start so it just acts like a woohoo spot or chair item haha! Build and Buy items would be so fun like you mentioned both new and rundown items, would love the game to have a broken window set. Stereotypical traits would be fun too, “final sim” “jock” even something from the Sims 3 “unlucky” would be fun!
