The Enclave are the remnants of the U.S Goverment and Military not to mention the most advanced and leathal force in Post apocalyptic america. Its interesting to see peoples opinions on the Enclave, they all justify the NCR, Brotherhood of Steel and various other groups. But in reality seen in the events of New Vegas the NCR isnt helping anyone lol.. they just take everything they can and are lead by a corrupt goverment of whoever holds the most wealth is king.
The brotherhood of steel is an advanced faction but they are not interested in saving humanity just the Tech that was left behind lol... in fact they seem to kill everyone just the same, but do it in a Knightly polite way lol... They are not out to save humanity and certainly not helping, they refer to the wastelanders as savages and kill anyone who posses any tech that they want. Just imagine your walking along a road with a nice laser rifle you just uncovered after days of scavanging your thinkg "Oh this will feed me for months when i sell it" then they approach you and shoot you dead and take it. Thats about as good as they will ever be..
Past the Enclaves first phase of killing all the mutants, phase Two rebuilding a clean peaceful world with no war or fighting basically it would eventually be like the Tranquility simulation without that nutjob Braun murdering people for amusemant lol..
God Bless the Enclave. God Bless America.
