it doesnt just have to be 100% completion (which I dont really understand if it doesnt add anything to the game)
it can be anything...somthing that might break your imersion or REALLY botheres you or you get annoyed if it isnt there
for me its the cutscenes being in sync...after a few bad experiences with a couple of games its the 1# I look out for/obsess over....scrutanizing thir mouths for the "tiniest" bit of deviation from the audio...when thats probably really not a good thing (and distracts from my enjoyment)
another thing is If I notice the same "set" NPC's or props over and over again to the point where it annoys me
