Ok I am 46 hours in my first play through I intended to play this as if i was playing it. I started working for house until he asked me to do something beyond my moral compass (bunkers destruction) and I tried working for the NCR who did not really like me at the time because i chose the quick revenge for my companion Cass I have now done every quest for the NCR possible and am a soft hearted devil the only one i have not finished is collecting irradiated dog tags because i can not find one of them. so in short house attacks me on sight lemon attacks me on sight and NCR doesn't trust me enough to let me interrogate the prisoner let alone continue the quest line so what can i do? I am determined to follow my own actions and let them guide me through vegas to see what the end would be like but i cannot continue the story I would start over but this is my 1st play through and I'm 46 hours in. any suggestions to how i could finish my story? i don't want to take over Vegas

Did you do all the NCR quests out in the waste land? I got in good with them before I ever got to Vegas.

Dunno about the other ones, as Im still fairly earlt in the game.
