Real Time Settler's port to NV?
Yup. Well made, though discontinued. I preferred the F3 version though, you could recruit anyone there instead of just using the stock immigrants.
Weapon Mod Kits Expanded?
Expands weapons in all possible directions. Also has the meshes made, so yeah.
After School Special?
Haven't really played it. However, while it looks well made, I just don't dee any difference from the piles of existing home mods. Besides, I never liked such mods, so I might be a bit biased.
Electro-City?
Last time I used it, it worked just fine. However, despite the humongous size, it just doesn't change much. Worthless unless you're going with a darker nights mod. And even then nothing special.
Got some recommendations of mine:
Project NevadaA big mod that adds various gameplay additions in a lore-friendly way. And everything is freely customizable from the main menu. Definitely great.
Companion Share and Recruit and
RobCo CertifiedAllows you to recruit any NPC and repair / build / upgrade all the vanilla bots and many new ones. Everything integrated nicely with the companion wheel and all.
Classic Fallout WeaponsMany of the classic F1 and F2 weapons. Polished meshes and all. Recommended.
And of course Fallout Overhaul Kit, but you already know about that one.
Everything works just fine with each other. Some compatibility patches needed of course.
Oh yeah, and stay the hell away from nVamp if you find it. It's a horrible, outdated mod compilation.
