I consider Nier Automata to be my favorite video game of all time, not because I think it has universal appeal and is perfected game design that is infinitely replayable (at least, not for everybody.), but for personal reasons. The messaging, story, lore, characters, music, gameplay, everything about this game aligns perfectly to check every single box for a game that I specifically would fall in love with.
To quote that one horror manga: "This is my hole! It was made for me!"
