Boooo!
100% completion or nothing at all!!!
I did say "right now"...
I know that someday after beating it I'll go back to playing it again and get that 100%. With as much as I'm enjoying Fallout 3, I do need to get back to playing other stuff too.
If you take all of the quests, you can get 100% your first time through. I did it in 60 hours or so. Less time than it takes to play through Mass Effect twice.
I already lost my chance on doing that. The "Strictly Business" quest in Paradise Falls failed because I rescued the kids and killed the guy that gave me the quest.
And right now, my Karma is up to the point that Fawkes is my follower and it's hilarious having him plowing down everything that gets in my way. And the stuff he says..."I WIN AGAIN!".
A couple of times he got a little too aggressive in killing, though, and I had to start over. When I was doing the Nuka-Cola Challenge, he was with me in the girl's house that was paying me for the Quantum and just mowed her down with a minigun. Funny for sure, but I hadn't finished the quest yet and had to start up from my last save.
Anyway, I'm on the "Shoot 'em in the Head" quest and have one key to find in Rivet City before reporting back to Mr. Crowley. We'll see how that plays out and then I'm going to meet up with the Brotherhood of Steel at the Citadel for the end-game.
