fair enough lol
Publishing a game on steam requires you to pay $100, and on top of that Steam takes 30% off of every sale. But Steam has Steam Keys, which are free to order for your game (after the $100. You can't escape that one on Steam). You can sell these keys on other platforms as long as it's not cheaper, and this way you get much more money off of your sales. It's our life as Indie devs.
