here is what i think would happen in 10 years
BOS:with enclave gone they would take control of the capital wasteland helping the people in it and then they would focus on getting rid of the mutants.
outcasts:they remnined at fort independence until it is overruned by the BOS or until they contact the original BOS then that would start a war
Talon:with ransacking water caravans they would get overruned and wiped out by the BOS.
Reily's Rangers:they would grow taking fort banshier for themselves then become a mititary force
megaton:would grow and taking springville would become the safest place in the wasteland creating their own authority and caravans
Rivet City: would then stop guarding water caravans since the brotherhood is big enough to guard them now they would try to get the aircrafts working then have outposts all over the country.
CCommons:would become the trading center of the wasteland creating caravans and then become the wealthist town in the wasteland.
tenpenny tower:would be overrun by ghouls then become the second and greatist ghoul settlement in the wasteland
big town:would be abandoned as the settlers would go to safer settlements
the pitt:would be overruned by the BOS and the BOS would see they were making a cure for mutantions and making a working steel indruisty they also try to do this and then in 20 more years the would acomplised that
or
i would take over the capital wasteland with an army of y-17 trauma harnesses,cyberdogs, and robo scorpions getting rid of all of the factions and make the wasteland a technolagy paradise
