I've said it elsewhere but yes, I'm interested in this. It definitely needs a new world. If they base it off of a more rural Brindleton Bay or the Windenburg countryside and make sure they have enough lots, I'll be happy. By that I mean, make it more like Brindleton Bay and less like Del Sol Valley in terms of the number of lots. Obviously, it would need large, scenic lots with whatever rural theme they go for.
I agree that they could allow sims to buy plots, fields and pastures in addition to the local houses. As mentioned, they could also bring back nectar-making.
There can be a stable that sims from other worlds can visit to practice riding as well. I want horses but I'd also be interested in other farm animals like chickens and milking cows. I'd also be interested in having actually farming and there could be farmer's markets for city sims to visit. I know they can already buy stuff at stalls, but it could be a more rural type of venue with different items and activities.
There would be new crops that aren't in the game. Essentially people could homestead and/or sell their items. The design of the world would be important for this.
