The other comment points out that it's only a case of selling steam keys where steam must have the lowest price.

I released a game a while back and while reading the terms it sounded like I couldn't link my Steam store page to another storefront where the game was available cheaper. Which, honestly, also kind of fair.

But again, I think that's really only if you're selling steam keys. If you sold the game DRM-free on your own website, I can't imagine they'd take down your company website.

If you link to an Itch page or something similar that might be a thornier issue because they're primarily a storefront.

I'm of the opinion that my game costs X unless it's discounted to Y. I don't see the appeal to the end user of having a dozen different prices on a dozen different storefronts.

I could see a situation where a developer wants to always earn, say, $10 from their game. So on Steam it might sell for $13, on another platform it might be $11 to show the difference in platform fees. But I wouldn't do that because it's putting me before my players, and that's not why I make games.
