I used to categorize manually, finished games going into beaten-replayable, beaten-100%, beaten-done playing, open-done with, etc.
Dynamic Libraries are helpful for sorting, but not a replacement for manual categories. A major down side of the dynamic library feature is thst it relies on the game page to be accurate to the games feature set. Often there are games that get a tag or feature thst is just false. This does not a good tool make.
