First of all, all of these sims are in .sim format, so you can just plop them down into your Saved Sims folder. I saved them with their CC, so if you have it, it'll show up, and if you don't, you can just change it and it won't be an issue. (EDIT: Generation four is saved all base-game.) Feel free to do as you please with them, and you can change whatever you like as long as you don't mess with their face. It'd be cool if you'd let me know if you're taking them, especially if you're going to use them in an online legacy/challenge/story/whatever. I'd love to see what they get up to!
These are my default eye replacements (Oh My Eyes). At the beginning I had a different one but I don't remember. I've also used these. I've changed them a lot. My default skintones are these bodies and these faces.
Some of the sims, specifically Alex, Lenina, Veruca, Nix, and Felix, are wearing a non-default skin, namely this one from GOS.
I'm not good about keeping up with my CC downloads. As such, I may not be able to tell you where I got their hair and stuff like that, but if you need it, ask me, and I will do my very best to find it for you. No guarantees though, as I'm kind of an idiot.
