I would never argue that Dick Richardson or Frank Horrigan alone could match up to the Master in terms of impact or cool, but I think that overall, the Enclave makes for a really striking satire of the US and its problems that it makes for a good comparison. Who do you think was the better villain faction and which represents fallout better as a whole? On one side you have the Master and the Unity. Gruesome, yet logical. The Master is trying to save the fading light of humanity by ushering in a new age without conflict. One people, united by his mind, equal with no dividing sense of self between them. They might be the best hope for the wasteland if it wasn't for their grievous oversight. He has an army of giant monsters that are strong and uniform. They don't need to think when guided by his voice worming his way into their minds. They are an enemy that hits at primal fears of humanity. On the other, you have The Enclave, the marriage between corrupt self serving politicians, military elite, and affluent wartime aristocracy, the very people who would start the war that would end the world, yet in those final days before the apocalypse they decided that they were too important to die, and thus abandoned America to its fate. The enclave is unreasonable. They will hear no counter argument and negotiate with no tribal terrorists. They are hellbent on destroying the impure wasteland for the "True Americans" even if that means killing every one in the wasteland and the world. They are a satire that reflects problems with America even today, they are the enemy that stays with us even when we stop playing the game. Which do you think is the better villain?
