Yup. I'm not a Dev, so I can't tell what their panorama looks like, I believe 30% of anything is hefty, but I also know that Steam has a platform and perks so solid that they don't have to worry about competition, since evidently no other consumer media distributor is willing to follow Valve's business model. Having said that, from a consumer point of view, I challenge anyone to show me a more beneficial platform than Steam.
