I crawled through the Steam partners documentation for a bit, and the only thing I can find about price-equivalency is in the Steam Keys section: https://partner.steamgames.com/doc/features/keys#3 https://partner.steamgames.com/doc/features/keys#3 As you say, it's basically "if you're selling Steam keys elsewhere, you need to be treating your product on Steam itself generally equivalently". It's written to sound flexible -- you can discount on different storefronts at different times, so long as Steam gets the same discount eventually. I didn't turn up anything for just selling your game without selling the Steam keys, but it's a big site so I might have missed it. (Or it might be buried in an actual contract somewhere, etc.)
