I can totally understand where you guys are coming from. Even I get burned out from time to time, but I always go back haha.
It is sort of like and ant farm, with all those little lives in your hands. I never really kill anyone, except ex-boyfriends.
I've been playing since the very first one came out, and have been hooked ever since. Even got all the stuff packs and expansion packs. I use cheats when building and decorating. I love to make huge, elaborate houses for my SimSelf. I'm very detailed haha.
If anyone has an account on The Sims 3 website, let me know and i'll add you as a friend and send you a gift
