I am a compulsive dork.
I have completed Fallout 3 on my Xbox 360. That's not the dorky part. I completed it having collected all 20 bobbleheads, and completing all quests except those my choices had locked out.
Well, there's always Broken Steel!
How can I be level 19, have the plasma rifle, the railway rifle, Sydney's Ultra SMG AND a Rock-It launcher, have explored Old Olney to Girdershade and STILL ONLY HAVE 5 Bobbleheads in Fallout 3???
