* slaver - in the chaotic world such as wasteland it is reasonable there will be slavery
* cult - the only cult right now is child of atom but in previous one we have more like cannibalize and vampire. Not sure is synth hunting/saving consider one
* vault - in compare to previous fallout the vault experiment seem to be much less evil and crazy
* random encounter - maybe I am missing something but I don't remember any random encounter on road (not counting random spawn). What I mean is something like Talo company got a bounty on your head, or some quest giver traveler like in Skyrim
* evil option - sometime you can be a jerk but almost every decision seem like good guy option. I kinda miss some evil option in fallout 3 that I sold the kid that I just saved to a slaver
What do you guys think?
