Ok so I decided to take New Vegas for myself but I am stuck sort off. I have to meet with all the different factions so I can choose which ones to leave alone.I am down to two,the Khans and the Boomers.What I don't get is I have already fought the Khans on multiple occasions and they hate,why do I need to get to know them?Then the Boomer,I pretty much got all I need to know about them when I approached their base and was almost blown to hell. So do I have to actually go and meet the groups or is there some way around it I am not seeing.If I do have to meet them I would like some tips on how to reach the Boomers with all four of my limbs attached.
