Oh Fred.. well thats the thing since it isn't that easy to come up with a Sims 3 Online mod or multiplayer whatever you wanna call it. The Sims 4 Multiplayer Mod was only possible because the game already had online components in it that were essentially just re-enabled. Sims 2 and Sims 3 however, never meant to be online games, therefore someone had alot to program to pull a mod like that off. I think just alone somehow coming up with a system that makes the game take care of the Sims actions of both the players in Sims 2 or Sims 3 will be a hell of a job.
