How about a swish pad of your own where you can stash your gear? That's very easy to get the hang of, and over the next twelve steps, I'll show you exactly how to build it. However, there are less ambitious projects that are just as rewarding. To build a full quest, complete with dialogue, missions and more, would be one hell of an undertaking, whether you have modding experience or not. It's precisely what you'd expect the app Bethesda used created the original game to be, which is to say fearsomely, terrifyingly complicated. You might not be able to teach these tattered scavengers to rebuild their world for themselves, but you can lead by example by using the GECK - the Garden of Eden Creation Kit.
Never mind rebuilding civilisation - most of these survivor-types are too lazy to even move the corpses out of the bathtub when they take a soak. One thing you'll have noticed while wandering through the lonely New Vegas wastelands is that the post-apocalyptic world isn't the most progressive place.
