I just don't have time to find everything in a game if I want to (esp the GTA games which were some of the last I've actually played through).

It was nice in games like Donkey Kong Country where a level got a "!" after the name after you fully completed it or in Mario World were levels with only one exit blinked yellow but levels with multiple exits blinked red. Those damn games that expect you to find everything without any "hints" like that are total walkthru fodder nowadays ;-)
