I never played Sims 1 and with Sims 2 while I did have CC, mostly houses and clothes from Mod the Sims, it wasn't until Sims 3 that I ventured to the dark side of mods. I didn't play with mods in Sims 2 because I was terrified of them, but Sims 3 was just such a troublesome, bug laden mess that I had to break down and try them or lose my sanity. The sainted Twallen at NRAAS was a godsend. I started with Overwatch and before I knew it I had the entire NRAAS suite. Then once I realized my computer wouldn't explode, it was game on! I played Sims 3 for 10 years, so when I started with S4 I knew I needed a MasterController expy, so I found MCCC. I'm pretty sure that one was first, but certainly not last. I'm creeping up on 2 gb in my mods folder for S4. Not as much as some, but plenty, IMO.
