Does anyone else here make OC's into sims?

YEAH, ABSOLUTELY. I even make texture edit CC for them!

Sometimes it's the other way around and my sims turn into OCs instead, but that's a different story. (pokes my icon - he's the reason i have vampire ocs in the first place, oops)

The ones here are ones I've had for years before Sims 4 came out; in fact I made them in TS3 too, at some point. They're this specific type of aliens I made up.

And that is barely a fraction of the OC sims I've made. ESPECIALLY if we're including TS3 sims, because oh my god I added so many OCs into that game. So many.

Also, The Sims is just great for figuring out their houses in general. Floor plans. Keeping things consistent. It's good. I actually have a friend who exclusively uses TS4 for creating his OCs and their houses; he's not as much into the gameplay part of it.
