Yeah, they both dislike mutants, totally the same goals right? Never mind that Styles theory rides on the team going to Navarro having no knowledge of Eden and the fact that his reasoning for them having no knowledge of Eden completely renders the point of a Chicago base as useless, something I find dubious at best; or the fact that the Enclave still believe in the principles of America, ie, DEMOCRACY and not fascism.
I like that "that Styles Theory."
We had a debate about this. My theory is adaptable. I personally like the idea that those from Navarro did not know about Eden and that they were just following a signal. Still it is also possible that those under Augustus Sir were ambushed by the MWBoS while they were setting up a base in Chicago. It does not matter if they knew about Eden or not. Eden can't help the Enclave when surrounded by an Army of BoS and Robots on their home terf. It would come down to make a deal with the MWBoS for safe passage or be gunned down there in Chicago and never making it to Raven Rock.
My theory is... Enclave left Navarro (knowing or not knowing about Eden) and were making their way to Raven Rock. They only had a couple hundred people if that. They get to Chicago. They start setting up an outpost. MWBoS under General Barnaky notice people with some very advanced tech in their back yard. They surround the Enclave. They don't attack outright because the Enclave can still cause alot of Damage and the MWBoS need every man and Robot they can get, to fight the Mutant Liberation Army. MWBoS give the Enclave a deal. MWBoS elders talk to Agustus and other Enclave leaders.
Enclave get their outpost and leave some men behind to man it (which they were going to do anyways). MWBoS get some new tech and research people. Enclave also could possibly get designs for their new armour in Fallout 3. MWBoS don't know about the Enclave because they left before Fallout 2.
Enclave move on to DC. They get their ass kicked once again. Remnants from DC go back to Chicago. Those left behind there teach them everything they need to know about the MWBoS and their long war against the Mutant Liberation Army. Enclave remnants see a chance to rebuild. They develope a new moto "If we can't kill them, we might as well control them."
As SavageBeatings put it. They can become the puppet master of the MWBoS and one day take over it.
Their alliance could be set up so the Enclave remain an independent body within the MWBoS and the MWBoS allow this as long as the Enclave keep helping develope weapons and many more Armour for the war against the Mutant Liberation Army. A war that the MWBoS have been slowly losing for over 80 years. Enclave remnants can finally turn the tide of this losing war.
Edit: I am also happy for the Enclave and MWBoS having nothing to do with one another. Only problem is Both Factions are in Chicago. I like the MWBoS and I want to see them again. I am also hoping the Barnaky Ending becomes the canon ending to Tactics. I don't want the MWBoS to be nothing but a small group in Chicago. People also want to see Enclave again at least as a small power. I can't see away for both Factions to be in Chicago without another BoS vs Enclave battle other than my theory, which to me is a win win. "Darker" more Kick ass BoS and Enclave Remnants regain some power.
