I started a new save where I'm building Newcrest to be a more-or-less all-werewolf town. Newcrest is short for Newcrescent, in this case. I only have Werewolves and Seasons, but in my dream version of Newcrescent that has all the packs, I'd be including:
Little Innisgreen and Little Glimmerbrook, since werewolves are said to get along well with fairies and spellcasters. Each would be spread out over two lots. One would be a small business that caters to both werewolves and the respective occult associated with the world. The spouse of the business owner would be the landlord of a tiny home village-turned-residential rental built in the style of the respective world (as lot #2).
A vet clinic, which is run by a sim whose spouse is a doctor. One of them handles dog health, and the other handles dog people health! I think I'd have one or both of them have the cure seeker aspiration.
A graveyard/memorial to those who died in the war against the vampires. (I'm still gonna do this since I have the Graveyard Lot Trait mod, but none of my ghosts will retain a spellcaster or vampire history aside from what I write into their story)
Clubs (read: custom werewolf packs). All the packs would have werewolf abilities as an activity, but I would also include:
The Howlers, a club that roars, hikes, rock climbs, and sings.
The Carnivores, a club that grills and abhors gardening, drinking coffee, drinking ranch nectar, and drinking tea. I think I'd require all club members to be gluttons as well.
Something something stereotypical alpha and omega dynamics. Could be a very romantic/woohoo-heavy club that might also get massages, or I could go just make a villainous club of alpha dudebros. Or maybe I'd make two clubs that hate each other.
A werewolf family who has an alien foreign exchange student.
A werefluencer (as inspired by the Ginny Di skit) as a celebrity with the Influencer, All-Nighter, and Squad perks
A Jacob Volkov expy who's a politician, as he wants to be in my legacy save
