Does anyone know if the game will be over once the main quest is finished, like in Fallout 3 (without Broken Steel), or will we be able to play even though it's done?
I believe they had that for FO3 and FO:NV (yes I know it wasn't made by Bethesda) because that is the way that Fallout games are; they have a permanent ending. And as for my opinion, I think it is ridiculous to have a permanent ending in an open world game like TES (or FO3, for that matter).
