There's the odd game that uses registry for the purpose of save files for some reason, which is stupid when you have several PC's and want to sync progress for the odd session. There's one example with a very solid puzzle game (Lyne; https://store.steampowered.com/app/266010/LYNE/) that used registry but I see they now have Steam cloud on the profile page but back in the day I had to export registry keys to not have to replay the same puzzles, not fun.
