Yep. Sell your game for whatever you want wherever you want. If you want to distribute your game via Steam (Steam keys), you can’t sell them cheaper than they are sold on Steam because you aren’t handling the distribution (which costs money).
Otherwise a competing company (like Ubisoft) could just make a 20TB game, list it on steam for a crazy price, then sell Steam keys for it on another storefront cheap; Steam will have to cover the distribution costs without making anything in return.






Have you ever bought a game via a Steam key? Those use Steam’s infrastructure for distribution while not providing them (Steam) any income.
As someone that has entered so many Steam keys over the years (over 1,000) yet only bought maybe 20 games from Steam I almost feel bad, but the dev was following the rules and Steam is okay with it (as long as they aren’t selling those keys for less than they can be purchased on Steam for).
