My game is having a lot of crashing issues and I'm curious if it is Origin that has borked my game. I was wondering if it'd be possible to uninstall Origin and still play my game or if it'd uninstall Pets as well.
Origin does not have to be running (even though it will tell you it does) for you to play.
Minimize the sims, close origins, play game.
If you still have issues, it has nothing to do with origins. If you don't.. problem solved.
