What have been some of your worse?
My first game I remember getting three 10+ dmg weapons and two Dwellers in my first 4-5 lunchboxes and thought that was great and to be expected..
But then I started a new game in order to be more efficient and I've had nothing but pretty lousy finds all along. So far I've been through about ten lunchboxes and had only a single weapon over 10 dmg (a 9-12 shotgun) and one Dweller (a level 8 with so so stats).
One time I got a box that had 2x 100 Caps, 1x 50 food, 1x Stimpack, and 1x Enhanced BB Gun. Man, I can only say that I was happy I didn't put any money into it.
