I learned how to mod back in the days of Sims 3 and have never looked back. :D I couldn't play a vanilla game if I wanted to, but I have reformed somewhat. I use only use Maxis match hair and no longer use the alpha hair, it is beautiful but files are becoming astronomical for pretty hair (47 mb). I made a deal with my computer, I keep my Mods folder under 1 gb and it runs nicely. :D
I too can't play without MCCC and a few mods not to be named here, mods mostly to do with gameplay. I've toned down on CAS cc and am having no problem keeping it controlled. Patches still make me tense though.
