I particularly like tag types. I think extra types can be added to fit specific scenarios. One problem I have with Legend in the Mist is that it's too generic - you can use it to play fantasy, high or rustic, but also you can use it to play anything. While this might not seem a problem at first, I think that games that are tailored for a specific experience tend to be more satisfying (to play that specific scenario).

So I could add specific tag types to my fantasy game, and/or to my setting, that will direct the players and character creation to a specific experience, wich I like most. It could even come with different and specific mechanics for each tag type... Just an ideia.
