Do you have any games that you like but you never finished for any reason? Which game is it? Doesn't matter how many times you play and replay it you just never get to see the credits roll.
I think Skyrim gonna be a quite common answer xD
I've started but never finished plenty of games but one always annoyed me till recently was factorio. I had over a hundred hours and I never even automated blue science.
Then a few months ago I said screw it, started a new save and over the course of 3 months and 150h I finally launched a satellite into space.
I am quite happy now that I did "beat" it but I'll probably revisit it soon, either to try improve my base or to play modded.
