But don't you get endings depending on how much you scanned? Or some other unlockables?
Scan whatever you feel you want to know more of. Scanning some enemies is extremely helpful. Also, later on through the game, you get to scan monitors and such to get a better idea of wtf happened in that room and so on.
It isn't much of a hassle unless you make it a hassle. Dont feel like you need to scan absolutely everything.
