I mean, there's a very real difference between moving on and forgetting. If you don't think LiS fandom is helping you realize or move towards anything, then there shouldn't be a problem moving past it like you've no-doubt done to dozens upon hundreds of other songs, movies and books in your life. If your mind won't LET you move on, then it's probably trying to subconsciously tell you something.
I always say the game is equal parts nostalgia and wish fulfillment. It either makes you reflect on what you had, or tells you what you want.
There is a nostalgia factor, but I've realized that the part that hurts the most is the scene at the bathroom in the absolutely-wrong-you-should-never-pick ending. Seeing Max there just broke me.
