You know what'd be fun? A stealth game where the story actually plays out differently if you reach certain parts of the game without ever having been detected yet. Like say, if Solid Snake gets halfway through the game avoiding every single enemy and never raising any alarms then when he turns up to the villains' HQ to eavesdrop on them they actually aren't even aware anyone's in the facility yet. All the ambushes they set for him simply aren't there because, well, they don't know there's even an infiltrator so why would they be mobilizing against him? The true measure of absolute success in a stealth game should be if by the time the end credits roll the villain still has no idea the protagonist even existed.
