Heck, Steam has one other killer feature that I wish more digital storefronts understood: if I want to play a multiplayer game with a friend, or even if it's just their birthday or I feel like doing something nice, I can buy a game and send it straight to their account as a gift. There's, like... zero friction here, it's a checkbox and a dropdown and done. This can help considerably with the income gap since it permits otherwise impoverished users to occasionally receive games from their friends, and the platform still gets a sale. I've lost count of how many copies of Magicka I've gifted to people this way, since it's the kind of wonderfully silly game you can pick up and enjoy without lengthy tutorials.
