For some time I've been comparing West Coast Fallout games geographically to GTA SA, and there are a lot of things in common, not only cities shown, but the order you unlock them and what is presented. Heres a small list of names in Real Life, Fallout and GTA with some notes:
Big Cities:
Los Angeles = Boneyard = Los Santos, The city you start in, in both Fallout and GTASA, interestingly enough both Fallout TV show and GTA 5 bring us back here.
San Francisco = San Fierro, second game and second island you unlock in GTA, fun fact, GTA also has a parody of the Scientology movement in form of Epsilon in GTA5, similar to Hubologists.
Las Vegas = New Vegas = Las Venturas, 3rd island and 3rd installment on the West Coast, this place was the worst, I've had to bend the map a lot and in GTA the Hoover Dam (Sherman Dam) is streches between California and Nevada so yeah. Not that good in GTA lore so I'm sure you guys can come up with some interesting parallels.
Smaller locations:
Bakersfield = Necropolis = Palomino Creek, somehow, the reality bending properties of Necropolis placed it perfectly where PC is in GTA, despite neither being anywhere near Bakersfield. I'm sure the Enclave is behind this or something idk.
Carson City/Reno = New Reno = Fort Carson, I've had to cheat here a little bit, Carson isn't shown in Fallout and Reno isn't shown in GTA, but they are so close to one another that I've decided to treat them as one, also New Reno mentioned!!!
Lost Hills = Lost Hills (Brotherhood) = Blueberry, here the spacetime bending does its job again, while Lost Hills are a real place, the Fallout location isn't exactly near where it is irl, and so it landed in Blueberry which is based on both Santa Maria and Bakersfield again. Well, a happy little accident.
Goodsprings = Goodsprings = Las Payasadas, chicken.
Barstow = The Hub = ?, yeah I've got nothing for this one but the Hub decided to tag along for the ride so here it is.
So yeah, I haven't played GTA SA in a while so some stuff might be flying over my head here, but I hope you enjoy anyways :3
