I have a few pack ideas:
Ancient Greece (instead of Medieval, because that theme is kinda played out, lets be honest).
~A brand new world without any cars or modern technology
~This would pack would come with some neat skills:
-Two Instruments: Aulos and Lyre
-Pottery: Sims can learn how to make beautiful vases in the authentic ancient Greek way.
Those are my ideas for that pack. Obviously it should have more than what I said.
Music Pack
~Just add playable woodwind/brass instruments. I'm not picky on anything beyond that. Lol.
Horse Pack
~Horses, of course, with different kinds, including ponies and miniature horses.
~Unicorn occult.
