I do not understand genre, so I do not know what to call my game. I focus on story, characters, plus game play that works. What would you call a game with tactical parts, with a bit of story, with possible battles as you try to locate your family.
The right kind of creativity is adding your flavoring and layering on tested and proven tropes, not tearing them down and rebuild things in your image. Just like how you don't cook eggs with a brick or a chainsaw, but instead learning on how to make your eggs look good and different than the other eggs.
