To be honest I wish they would do that and separate the East Coast fallouts from the West Coast in terms of canon. Would resolve a lot of disputes between the "fans" and the other "fans".Fallout 1 and 2 and F:NV are now completely not canonical, with only Bethesda titles being the only canonical ones in the entire series.
My sentence will resonate.
Fallout games from now on will only be mobile apps that are free to play and have timers for everything. You can pay real money to reset timers and to buy new hairstyles and clothes.
