I'm sure everyone has that game installed. The one you click on in your Steam library that you just want to play. If you ever format and reinstall your rig, it's one of the games you install first, but loading it up and seeing the date on the save file instils a sense of dread. For me, this has been NieR: Automata.
Now that I've found the time and play through the main routes of the game, I'm not sure what took me so long.
