i don't know if they will do that but i'd love the idea to turn the packs into one pack
like you said: Vampires, Realm Of Magic, and Werewolve and maybe even Life and Death because they're all dark themed kind of pack and maybe Crystal Creations, Spooky Stuff, Paranormal, Goth Galore and Grunge Revival since these are giving dark themed vibes and could've match with certain occults
Vacation packs that can turn into 1 pack: Outdoor Retreat, Jungle Adventure, Strangerville, island living, Journey To Batuu, Snowy Escape and My Wedding Stories
Love related packs: Romantic Garden, My Wedding Stories and Lovestruck
Family packs: half of the packs which is family related (even some kits)
Works and Businesses pack: Get To Work, Dine Out, Get Famous, Moschino, Discover University, Tiny Living, Nifty Knitting, Eco Lifestyle, High School Years, Home Chef Hustle, and Hobbies & Businesses (possibly even some kits)
they're just to name a few, maybe i'm missing some packs that can be in the category i've mentioned
i honestly don't know why they make things a Game Pack if they're no longer making ones? (same with Stuff pack)
they should either be in Basegame or in an Expansion Pack now that we have lots of packs (and kits too)
i doubt it will happen but i can only dream right? i swear they could make some packs into 1 pack
before doing that, the team should fix the bugs and add more things that aren't in that pack yet first (refresh/overhaul) and later make it into 1 Expansion Pack
