Knew Fallout world since around 2001-2004 but mostly stuck to french fallout communities. (my english was much lower)
Apparently, i registered in 2006, mostly to download tons of mods for Fo1-Fo2-FoT which only i tried a few. Also search for help in modding, but mostly ignored the rest of the website.
In 2013-2014, i changed my gaming rig and finally tried Fobos-Fo3-FoNV. The first two were huge disapointment and the third one was a mixed bag, in which the awesomness is mixed with the filler mania. I lurked almost all french/english communities to share opinions about those three games. NMA is not the only community i participate in since that time, but still one of my favourites. The discussions are usually in-depth and troll-free, contrary to some other communities. Although, i regret that you don't do more coverage about the other Fallout-like like Age of Decadence or Underrail, and spend too much time talking about Beth. If Beth doesn't bring satisfaction, look for someone else more skilled.
On the other hand, i mostly stick to a french community which is a bit of the opposite. The conversations rarelly have the same depth, but the community deals with post-apocalyptic indie games almost as much as it deals with the licence new tites. What brought us together was post-apocalyptic worlds and roleplaying games, not just a brand.
