Remove "Indie" as a genre
According to contribution guidelines, "Genre is the first tier in our 3-tier categorization system. Choose the most fitting genre(s) to broadly describe the game."
"Indie" is not the primary, broad description for a game. Maybe in 2007, but not today. They are puzzles/platformers/etc before they are indie. Indie is better suited as a keyword, if anything.

This is taken directly from our Contribution Guidelines, under Categorization.
We do have a revamp of our Themes/Genres/Keyword feature, it's a large undertaking that needs planning and is in the ideation phase at the moment. Expect to hear more!
Where did you read about the 3-tier categorization system? I tried looking it up the block you quoted on Google, but only found a link to your comment.
