1. ...and All I Got Was This Lousy T-Shirt
Covered in both your own blood and that of the Deathclaw family you've slain, both your legs and arms crippled and completely high on stims and drugs that give you stat boosts, you stumble back into the camp where the old lady moaned on about the Deathclaws killing people, wanting your just reward. After talking at length about how you've saved everyone and you've gained good kharma, the kindly old woman presents you with three bullets, a bottle of Nuka Cola and your very own pool cue for use out in the Wasteland! She spoils you, she really does. For an enterprising Vault Dweller constantly on the move looking for new and better gear, such a reward isn't going to cut the mustard after the hardship you've just faced. So it is that the kindly person who rid the township of their Deathclaw problem then goes completely nuts and kills everyone in sight as a result of getting an absolutely shi**y quest reward. After everyone's dead, you loot their items, steal their cash and wander off into the distance with your middle finger stuck in the air before a Deathclaw you missed comes out of nowhere and swiped off your head with one move.
I do hope you've enjoyed these unfortunate consequences of living in the Fallout universe, but I'd love for you to expand further on these and add your own in the comments below! If you do, Fallout 4 will come out sooner. Just saying.
