I'm someone who likes to go back and re-read, re-watch, and re-play. I think a big part of a thing's value is whether I can enjoy it all over again. The best games, the best movies and shows, the best books are those that I can go back to and experience all over again without feeling like that experience is ruined. In a book or story in general I will notice details I missed the first time around, in shows/movies I can compare the characters at different points in their journeys, and also notice bits I might have overlooked the first time around. And with games, I will play it differently, try other tactics, make different choices and see how that changes the experience.
