Just thought it'd be real useful. Right now there aren't that many tags you can give to games and there are some games that can fit into two categories, so would be nice if categories could be tags as well. For instance if someone made a StarWars game it'd probably be in the fanfic section, but it'd be good if you could tag it as "SciFi". Or if a Fantasy game was based on the story of two lovers trying to save the world together, would be nice if you could tag it as "Romance" too.
