Well here’s another fun fact about steam for you then, you can sell your game on steam and retain the full profit of the sale by selling steam keys on other platforms like itch.io or humble bundle. The only stipulation to this method of sale is that you have to sell it at the same price the game is listed on steam at. Steam does not take a cut of steam key sales and encourages developers to distribute steam keys. They are free to request from steam and you can request however many you would like. No other platform does this.
Deluxe editions of games are anti-consumer even if it is an upgrade. Just sell the whole fucking game to me or don’t sell anything at all.
