Well Denver in lore that is confirmed. I still hold Van Buren as proper but is refutable like the Joshua Graham from VB is no longer true as Joshua Graham is in Fallout New Vegas. Still that's been touched upon needs correction like Denver as it is referenced in Fallout New Vegas. Denver isn't completely changed from VB it is just confirming that the Legion is in control after they beat back the Hangdogs. Pretty cool they subdued them by throwing their dogs into the fire. Your choice really, I'm not saying Cyberdogs are non existent but rare. The Chosen One had two accompany him I think that is the dogs that accompanied him. Well when the Synth in Fallout 3 tried to get away the man reprogrammed him and changed his face was more interested in seeing the Institute's secrets as they're very much unknown to the people of the Commonwealth and less so to the people of DC. There are people who can do that stuff but it is a rarity, if the Railroad commissioned him once though I'm sure they could do it many times over, if he's still alive as he was pretty old in Fallout 3... The Enclave tried before to get the Deathclaws subdued but it didn't really work that well if they got damaged or like what happened in Fallout 3 when there was a chip or something that identified the Lone Wanderer as a friendly. If the Brotherhood had that once they could replicate it and do it over and over till the Brotherhood is identified as friendly. Better to just kill all the Deathclaws. I'm not sure what to think of it because most plant life died... Because of a Nuclear Winter... Some certain places like the Grand Canyon were shielded from radiation a bit and died off quicker but New Vegas a place that I don't think had a direct hit had very little plant life, it did thrive in some areas but majority of plant life died. I guess some areas that were like a jungle might have had some way to survive but I ain't a botanist... If we use the idea of Florida's actual lore from I think Tactics II there was a G.E.C.K. that got damaged or irradiated, I can't really remember but that is how the mutated plants came around in Florida. I feel like playing Dynasty Warriors 3...
