Essentially really liking a game, remembering liking a game, or having fond memories of a game, not because the game itself was really good, but because of some other reason?
For instance, I have fond memories of Ghost Recon Wildlands, not because the game is amazing, but because when I played it, my wife had went out of town, my kitten had just had surgery so she had her cone on and had to be taken care of, and I had just had dental surgery so I was just chilling at home playing Wildlands for like a week bonding with a little kitten that I had previously had no interest in having anything to do with.
