Hmmm personally I like The Character Build group, not for the sake of playing the builds, but just for the fun of reading great ideas. I also very much enjoy the occasional discussion in the forums and whenever there is a competition I try my best to enter and contribute. I also enjoy the blogs, and lore posts, however I'm more of a TES guy so I tend to keep out of Fallout 4 stuff.
Which reminds me: I stumbledes across this D&D homepage (https://dnd-5e-homebrew.tumblr.com/) and thought it could be cool to use the same concept in some way? The layout of the pages are easy to make and so forth... just a thought tho.
The Roleplay group is my regular haunt, love reading old profiles and guides to remind myself of all the great ideas that've been had, and the evolution and increase in quality from back in the day to now.
But that doesn't mean I don't spread my wings a bit. I'm in the Workshop as often as possible, although I don't comment much I like to see Works in Progress develop and see if I an add a little something to them. Skyrim Character Building, Lore, Tips and Tricks and the Forums take up the rest of my time, although I wander around to every part of the site every now and then.
you can find me in da club, bottle full a bubb...
Wait that's not right :) Well duties have me hanging around Fallout CB and the Hub. I keep tabs on SKyrim CB too and frequently comment on the Skyrim Build recommendations thread...there's just so, so many quality builds to bump!
Oh, and Fallout and General Gaming Forums. :)
