I would like to see the Enclave change to a point were they no longer care that you arn't pure blood. Still the Enclave is to weak to become a power in another Fallout Game. A remnant group that lets you help them do something that is not "Take over the World" would be interesting. Just as long as they are just remnants that know they are dead as major power. They should not be brought back as a major power just so you to can get the chance to help in their plan to kill everything not Enclave. It would be the end of Fallout is they succeed. They are remnants now, nothing more. If you want them back as a small remnant faction with no plan to kill everyone that is one thing. Wanting them back as a Wasteland Super Power is another. Unless you want them back as apart of a former wasteland super power, I will support that
If they do come back as a super power "main bad guy" in a future game I demand Bethesda to do the Following.
Their new base is Acme Labs. Enclave President is "President Brain." His military leader is Colonel Pinky. At some point in the game Colonel Pinky asks President Brain. "What are we going to do tonight Brain?." and Brain responds "Samething we do every night Pinky. Try to take over the World!"
Maybe as a reminant group that try to live up to the ideals of the Old America, and are trying to stitch it up with the fabric thats available.... The "New Republicans" or something, kinda like the Followers of the Apocolypse in size, scope and action who use their knowledge to do good, and sell people on an almost religous idea of "the union".
Maybe even a few tribals praying to Ex Presidents.... I think I may have just jumped the shark with that one.
I could see that working.
