Horse Ranch - I love Chestnut Ridge, nectar making, and horses. So much to love about this one.
Life & Death - I play with aging off so death isn't a thing in my game. But I love Ravenwood. Mourningvale is awesome for vampires. It's altogether ooky! If I could redesign Forgotten Hollow, Ravenwood is exactly what I would want it to look like.
Lovestruck - Romance is a big part of my gameplay and stories. I like the expanded options with toto's, romantic satisfaction, etc.
Growing Together, High School Years, and For Rent - I really don't have an opinion of them. I don't use them very much.
***Businesses & Hobbies - I can't rank it yet. I've downloaded it, but haven't really played it. I had a quick look around Nordhaven and that's it. So far. There are lots of things that look interesting, and I have big plans for it. But I can't say where in my top 4 it ends up. On just potential it could be second or third. I just don't see anything short of a band pack pushing Horse Ranch out of first place.
