Reilly's Rangers. I'm a gun nut, radio operator, survivalist, and I like how their base is hidden.
I think combat armor looks cooler than power armor, too.
I think I'd have to join Paradise Falls. Being severely mentally unstable and addicted to caffine I do tend to rant and rage and go psychotic with 'Vengeance' and the only people who really appreciate some one like me are the Slavers.
Can't go to megaton as their all dead nor tenpenny Tower (both ghouls and humans are all dead). Just thinking... what happens if you go psycho in the Citadel, can you still complete the MQ?
DIE, DIE, DIE, EVERYONE HAS TO DIE. except the little children of the world. EVERYONE ELSE DIE.
