It's something I've probably felt before subconsciously, but not seen or thought articulated until this game. The way your favourite RPG follower - after you've finished the companion quest and exhausted the banter interjections - becomes just a pile of stats. The way Dark Souls, after you look up all the maps and secrets online, becomes just a video game. And also I think, to a certain extent, the way your takeaway from an ending can diminish if you look up all the other endings and permutations afterwards.
But also, I think, on a more general level, the way especially achievement hunting and that sort of approach, 100%-ing, turns games from artworks into checklists. Even though I've never been a platinum hunter, I've definitely had experiences where I've let myself wear myself out on a game by trying to be too completionist. But maybe Titanium Court has taught me to be comfortable with leaving a few more stones unturned.
