From my understanding the only time a Dev can’t sell their game for less on another store is when they are using a steam key to redeem the game.

Hey there. Actually, this isn’t true. This is the case regardless of whether a Steam key is involved. Games on Steam need to be the same price (or lower) as other stores. I’ve found this out a little while ago and compiled my findings in this thread (plus some helpful comments, including from developers confirming this).

Essentially, Valve does NOT allow the savings of putting your game up on a store with a lower fees to go towards the customers. They however don’t care if the developer or publisher pockets the difference… Something about “not putting Steam customers at a disadvantage”.

I ask you to please not repeat this misinformation, as I have in the past.
