utterly ridiculous. that was the entire appeal of ground zeroes post main op. It was the reason it was replayable for 100 hours on it's own. It's the reason I keep going back to each metal gear solid game and have beaten them all many times. the more you know the mission area the more fun the infiltration becomes.
Good for you, I hated that about GZ. If I want to have fun, I replay the mission and try something new, but during my first playthrough I want to be challenged and I do NOT want to know how to move and where soldiers are placed, I want the feeling I had the first time I sneaked in that location, you know, that excitement you get because you're afraid to be spotted at any time and you don't know where to hide if shit goes down.
