So you've been able to convince yourself to play without mods altogether then? I've heard some people claim that it's totally impossible to play this game without mods, but that can't be true, because I've never had any mods or 3d party CC, only EA made things, and I can still play it. Of course I experience some lag and freezing now and then, but for the most part it's okay.
Anyway, good luck with your new Moonlight Falls attempt!
It isn't an easy task. No, it's not impossible... but have you ever played the Sims 2?
For me, when I was first introduced to the Sims it was to the Sims 2, and I played that like crazy and saw ads for the Sims 3. I remember thinking: I'll never play that, it's practically the same thing!
Well, when I did end up trying the Sims 3, I just couldn't play the Sims 2 again because the Sims 3 was all the improvements I had wanted to see in the Sims 2.
Mods are the same way for most people. It introduces gameplay aspects that people desired to see in the game to begin with (or fixes issues that people didn't want to see) which is why so many say it's impossible.
I did stop using mods and CC (which made me cringe to get on and see all the damage of "replaced" items) and to be honest, I haven't noticed much of a difference in my files. It's almost disappointing because now, instead of automatically resetting Sims that are having problems, the game just has them sit there. The freezing occurs a little more now, but it always corrects itself after a few minutes of waiting instead of just running smooth like I'm used to. I'll try a brand-spanking-new file and see if the speed/everything else improved overall and if not then I'll probably crack and put my mods back in because if my game isn't improving from them NOT being there then my resolve breaks a little bit.
