First sorry for bad english I want to ask before the DLC when game fnished we cannot continue the game after DLC when I fnished game(the main quest) game is over and I cant play again ? or game is going on ? :sadvaultboy:

You can't.

You cant ? Game is becoming non playable from my fnished save again ? :S

Yes, the game ends.

You have to reload a save game from before the 'point of no return'. When a message box popped up saying there was no turning back and you clicked on it.

Ahh okay thanx I hate that :S :flamethrower::cryvaultboy:
