Once steam agrees to host your game, my guess is they want your customers (and indeed ALL customers) to think of steam as the place to store all their games. The biggest hurdle is getting your game on steam at all.
you can buy a game on Humble Bundle for $1 (or often even 3 games) and the slider there does not say *any* of that money goes to Steam you can buy a game at GameStop (of which Steam got no cut of)and then activate the Key on steam and never pop the physical disk in your computer I don't know for sure but making some educated guesses based off of things like Humble Bundle and purchasing from GameStop I'd guess it's basically the 30% steam cut per key, but I want to know for sure from someone that has already tried it. I'm planning a KS, so I'd like to know what the cost of requesting a Steam key is to add it to my budget.
I've searched all around and can't find anyone that has answered this question. The subject is pretty much self-explanatory.
