The basic overall concept of the game, is to imagine it starting around the time of fallout 1, NCR is still just Shady Sands, Enclave and BoS and Mutants have their starting bunker etc. But by F2 BoS and Enclave had multiple installations, and NCR held most of the area of the F1 map, by FT BoS have sent an expedition east, and by F3 both enclave and BoS have full bases in the east, so the expansion mechanic of Civ is completely valid in my opinion for a Fallout TBS concept.
Balancing between factions is still to be done, but when I get the next version stable .dll issues I am battling through, a lot of new things will be available, such as the raiders having many negatives, but a big bonus to pillaging, so for them running round destroying improvements should be very beneficial to their overall strategy (still working out if/how this will work exactly).
Enclave and BoS gain access to 'pre-war' tech such as a limited supply of power armour earlier than other factions. More things to differentiate the factions will be added later.
I don't want to split the tech tree as you suggested, because it is very difficult, but different factions will get different benefits, units, negatives, buildings, for each tech on the tech tree. So the benefits of a technology will vary for each faction. Tech splitting, could be achieved by giving different factions different starting techs that are prerequisite for the next, thereby opening up different streams for different factions, but at this stage the game is not large enough to require that.
The answer to the BoS question about their tech, is both. Many things they simply salvage from the old world and put back into use, but they also seek to gather the knowledge and 're-learn' what is out there and how to use/make it. Case in point is their desire to obtain verti-bird plans from the enclave in F2. In F3 the 'Outcast BoS' are more than happy to trade simpler tech such as bullets and explosives I think, in exchange for the more complex techs out in the wastes, this suggests a certain level of manufacturing avaible to the BoS.
