Depends on the take of the game. I'm pretty sure that there could be good gaming mechanics but story wise is arguable due adaptations from shows or movies into games are typically not all that great and are filled with fillers that do not really add much to the story itself. But ultimately, I think that an Avatar game (whether it be for Aang or Korra) would be fun just to play for fun. I think that they could probably make it into somewhat of an open world by allowing players to choose different areas of a map which may resemble the traveling they do and gain an experience within their world through the freedoms of a game.
I would have to say that I would like to play it but ultimately, it all depends on how such a project is dealt with.
I said that because people are making jokes about them because he turns into animals and would probably be too much. These jokes usually consist with her being scratched up but my point was that she can also be quite dangerous due to being a demon. I never made any fan fictions about them, just making a statement based on the jokes.
