I'm thinking about what's after F:NV , I wonder what it will be if you have any ideas of your own please comment

Besides DLC for New Vegas the next game will be Fallout 4.

Oh, the possibilities...

Fallout 4
Fallout: Project Anchorage
Fallout: Big Sky
Fallout: The Great War
Fallout Survival

I'd like the next game to focus on one of the other 'corners' of the continental US. Fallout 4 in Washington state, or centered in New Orleans would be most awesome.
As long as they don't put one outside the US, then I'm game.

I say the next fallout should take place in the Midwest Chicago their could be some nice leftover skyscraqers.

Wouldn't mind seeing a vault or a shelter that is not an experiment or messed up. Maybe, a vault that was not built by Vault tech either. I doubt, Vault Tech would be the only company building shelters especially when they only seemed to care about saving the more important people. They saved only ones they seemed necessary yet, led most to their dooms. Stupid.

i agree, i want fallout 4 to be mostly urban/city/industrial area, kinda like GTA, if anyone ever watched the movie "the omega man" or "i am legend" something like that, not out in the wastes.

Fallout Tactics partly took place in Chicago, so Chicago has already been done. I don't think it really needs to be revisited.

I'd like to see part of Canada. Maybe explore Toronto (unless Zeta fried it off the map. -_-).
