Prices range from free to $9.99, with Stereo Aereo coming in at $3.99.

Because I'm not an Insider, I wasn't able to find any of these on the Marketplace home page, let alone a Creators Collection tab. You might be able to find them by scrolling through the "all games" tab, but without a way to order alphabetically, it's anyone's guess where they are on the page.

I was, however, able to manually search for each game by title both on console and the web. If you're feeling adventurous, hit the links on the game names above and give 'em a shot.
