What online features would you like for the sims?

Honestly i play the sims freeplay and the sims mobile so in my opinion even if there was no online multiplayer or local multiplayer it would be cool to toggle on and toggle off "online mode" that would give your sims the ability to travel abroad to random player's worlds and interact with their sims to make online relationships and if you are playing in your own world that you have a chance to see other player's sims visiting your world that way the game can be more lively and you when your sims are using the making penpals and chatting online interactions on the computer that you have a small chance to have a random player's sims as a penpal and the random player's sims sent postcards from their own worlds etc etc. Sadly i doubt this will happen but this has been what my idea thought of
