I got the mod bug again, and as usual it's the smallish hideout/homes that I keep tinkering with.
so what do you look for in such mods?
What features or details do you really look for?
I'd want a very immersive, atmospheric and spartan starting out camp. It should be available right from the start, situated in Springfield or close to Megaton and basically just have a rundown camper, a refrigator, a burning barrel etc. http://www.fallout3nexus.com/downloads/file.php?id=2115 actually comes pretty close. It should look like something a scavenging homeless has set up for a while.
Basically, I love to check out house mods, but my chars always end up living in the Megaton Home anyway. I'm just like that, with Oblivion and Morrowind as well. Of course, the Megaton home is available very early, but with some chars it might take a while. And my chars are always desperate for a home right from the start. Plus it should be close to "home", i.e. Springfield, Vault 101, Megaton. I tried out an Arefu house mod, which was really nice, but it just felt completely off.
Another thing is that it always feels better if you have to do something to get something. For a small camp it could be killing the former, crazy and aggressive tenant. Small quests are also OK, but one thing about house mods is that you want to check it out ASAP (in order to know if you like it or not) - so involved quest lines can be a bit frustrating IMO, at least the first time.
Anyway, I'd say that for Fallout 3 house mods I prefer ones that goes with the post-apocalyptic style, i.e. rundown, mashup of findings, ruins etc. Doesn't necessarily have to be camps or shacks. I could imagine a cool, spartan home in a large partially bombed out house, for example.
Basically, besides a cool concept, I think it's almost all about detailing, cluttering, atmospheric lighting etc. Well, it has to be practical and compact as well, of course, but it's the detailing that makes it.
