For the first six years, I played a completely vanilla game. Now, I have exactly one Mod which keeps townies/premades from bothering my Sims. That's it! However, I do have a little CAS CC. But, still less than 20, including the Mod. I'm not opposed to getting more, I'm just taking it slow. I went crazy (10 gigs worth) with CC/Mods in TS2. I don't want to end up spending most of my time 'shopping' rather than playing the game, which is what ultimately happened for me back then. :)
