In the beginning my character sided with Khans, FotA, NCR, Independent towns(GS, Prim, etc),
Was trying to understand the what the CL wanted though the middle of the game and stayed on polite terms with them for the most part but at the end I obliterated them.
Powder gangers just a bunch of thugs, that pissed me off and that no one wanted - Long story short their all dead.
Later on through the questline I didn't care for the NCR and it was a bumpy road between us
Joined the Kings and peacefully solved differences with them with the NCR squatters
Veronica my first humanoid companion I came across I got along with well enough and tried to help the BOS be more helpful to everyone but ultimately this lead her to become an outcast. I allowed the BOS to survive for Veronica's sake. And a main reason why I decided not to join House and this lead to the turning point of me taking things into my own devices.
I helped the FtoA in anyway I could.
Talked Legate out of war (for the mean time) and saw his armored butt run like a little girl.
Ending:
NCR left, for now
Vegas became a breeding ground for chaos and it seems I did more harm than good for the followers (nice to see a mixed ending here, (things turning bad and whatnot wether you helped or not). Even though those securitrons should have easily kept order.
Powder Gangers - No one misses them
BOS- Took over Helios one after NCR left. Wonder what they plan to do?
NCR squatters and Freeside got along a little better(at least some good)
CL went back to the East to concentrate on their rule. For now...
Kahns left the area to become a great clan of warriors again terrorizing the (I forgot where they went).
Good Springs gained more trade due o more traders taking their road.
Prim has a hard but fair sheriff.
Hope I didn't forget anything.
What happened in yours?
