Let's see. I really love Fallout. I think it's the most amazing WRPG series ever!
In Fallout I prefer Unarmed combat. Melee is fine. Guns are meh. I hate energy weapons and explosives.
I love the Brotherhood of Steel! I'm not sure why, though.
I have played Fallout, Fallout 3, and Fallout: New Vegas. Not in that order. I plan to play Fallout 2 someday, but I know of its story. I like Fallout 3's side quests way more than the main quest line.
