I'm playing through Fallout 3 again.
This time I am concentrating on the side missions more, and intend on visting every location on the map before I pay more attention to the main storyline!
Amazing how quick you can level up second time around, as you make better decisions with perks etc, and have a better grasp of the controls etc.

This time I around I have had no issues with bottle caps, ammo or stimpaks.
I have nearly 15000 bottle caps and around 80 stimpaks in my posession right now.
