Personally i really dont want any enclave in this game but what are your opinions and ideas?
The Enclave as we know it, no. I think it would be cool if it was like just a small group of people that once were in the Enclave, but since the destruction of the Oil Rig, they are mostly scattered, and have settled down. After all, where are we going to get our advanced power armor?
That, or if the Enclave does return, just not the "Kill everything in sight" Enclave present in FO3.
Oh yeah, and I hope that the Enclave won't be significant or involved in the Main Quest.
