re-experience those nostalgic video games, movies, etc. and realize just how bad some of them were.
For example, LOVED Goldeneye in the N64. My favorite game by far for quite a good stretch of my childhood. After then moving on to play games like Halo, Call of Duty, etc., Goldeneye is unplayable to me now. Tried playing it multiple times, just doesn’t do it for me when compared to the newer generation of shooter games.
