That's some awesome advice! So often I see a fan-game of one of my favorite stories/characters only to be disappointed as it's just another rehashing of the same old story. Don't get me wrong, I love the story and the characters, that's why I'm a fan. What bothers me is having someone who has the creative freedom to make a fan game and show their love and dedication to the world by making another story that fits those characters or world. A good example of this is the Pokemon PC game being developed on this site, by Ratty524. It's a true pokemon game, but with a new story and even new pokemon created by the author.

I believe these kind of styles are the best kind of fan game. You are showing the community and even possibly the creators that you love their world so much that your mind was filled with ideas of the way things can go. Sure it's not cannon, but sometimes the side stories are the best.
