(More Borderlands spoilers!)
But storyline deaths are permanent. You'd think T.K. Baja or any one of those Atlas commanders would have registered at a New-U station sometime.
I think I went off on this before, but, it all made sense to me once I noticed the brand on all those New-U Stations. They're Hyperion-made. Hyperion as in the company that basically led you by the nose straight to the Vault so you could off the Gene Worm and let them loot the place in another 200 years or so. And
there's a New-U Station right the fuck in front of the Vault door.The Vault Hunters aren't super-special badasses. Anybody could have killed the Gene Worm with infinite lives. So the question is, why didn't they? Because Hyperion wasn't going to let Atlas goons and raiders use their super-special immortality machines to do whatever the fuck they pleased, of course. They needed to get some unallied, treasure-obsessed, easily-duped thugs to clear out all the other factions gathering around the door without stopping to figure out that the weird Sadako voice might just be moving them around like suckers. Long story short, the PCs were handpicked, giving
exclusive access to the magical respawn machines, set loose on the world, and in the end paid off with a pittance of cash so that they wouldn't start asking questions once the whole quest chain was done.
As for why there are so many bandits and relatively few normal NPCs: supposedly there are still bastions of civilization left on the planet,
you just happen to be fucking around in Space Afghanistan.
