If you like itch.io's model for selling and publishing games of all sorts, you might be interested to know that Evil Hat has published a big batch of Fate games and supplements there, most as pay-what-you-want. It's a bunch of great stuff, but I'm personally excited that you can now pick up Sails Full of Stars, Ghost Planets, and So the Story Goes on itch.io.
I think itch.io is an exciting space for game designers right now. Its hosted game jams are fantastic for spurring creativity and building community, and the process for publishing your own game on itch.io is super friendly. It's also an excellent alternative to Steam if you're into computer games by independent developers.
