Oooooo maybe we could collab and share ideas!!! I honestly had a very similar idea to this (here it is)
Ok so I was thinking and now that the cottage living is coming out we could include another farm animal such as horses. I was putting together an idea where theres a new world with three areas of land.
Land 1: A wild west themed one, cowboys, goldmining, saloons, pistols, deserts which you can move in and try not suffer from heat and lack or water and more
Land 2: Similar to the cottage living but there's a forrest that surrounds it that is inhabited by faries, elves, pixies and what not. There's horse trecks and rivers that you can walk across etc.
Land 3: Its not exactly a land based on a town but more of a riding academy. Sims are able to board at the academy, buy their own horse, compete against other simd and learn jumps, dressage, barrel racing and what not.
In Land 3 theirs a few houses scattered around but mostly its the academy and a competing area for competition. Lanf 1 and 2 have a set rivalry and most of it comes down to riding to see who's the best.
I have soooooooo many more ideas for this but I don't want to spam anyone XD Let me know if you want to hear them and have any other ideas!!
Oh and of course we can't forget about the horses!!!
Also if u see this around ive already posted it but I only just saw your idea!!!!
