What online/multiplayer options would you find acceptable in a Sims game?

I love the gallery but beyond that it’s Keep Out. I don’t share my actual game with anybody. It’s 100% my world my way, I don’t want anyone else mucking about in it. I let my 14 year old niece play my game sometimes when she’s here. After I have taken out my sims folder, locked it on a password protected external hard drive and generated a new folder. Because yes, I am that protectionist about it.
