I was thinking about Makin' Magic, and how the spells available included things like turning pets into human sims, and using an item from Superstar to power a fame spell. Back in sims 1 and 2, people were okay with packs interacting with elements of other packs, and sometimes actively supportive.
I'm not a fan of MFPS, because it felt like they held back content from C&D in order to fill out the pack without adding anything meaningful. But I'm thinking about magic, and how we won't see fame affecting spells, weather affecting spells, or anything of the sort because those would be one pack requiring another. So how much would you be okay with elements of one pack being specifically made to involve elements that came in another?
