I tried to look up what Steam's profit margins are, but I can't find any good information on it, just a lot of confused people pretending as if they're an authority on Steam's finances, but who don't even know the difference between revenues, profits, and commissions. Does Steam have a high margin? I don't know. It could cost more than you think to run Steam. Or maybe it costs a lot less - I really don't know.
