I just can't conscientiously go along with House after what he does to the Kings and the BoS, the two most awesome factions in all of NV.
Two Things. If you finish G.I Blues and have the King make the war with NCR citizens even worse, House actually lets them live and maintain control of freeside. BoS? I dunno why you'd want to side with them. Mr. House makes a good point about their faction. "Fanatical Terrrorists, obsessed with technology."
