I think it would be nigh on impossible for a developer to validate games 100%; the developers would never get the game through the door and out to market. To go everywhere & do everything a player might is not feasible. Take Skyrim & Fallout 4 as examples. Massive games with multiple scenarios & outcomes. Patching is an inevitable part of the gaming process. Just imagine how bad things would be if they didn't provide patches?
