ThreadTim Sweeney: “If Valve commits to a permanent 88% revenue share, we’ll stop making new exclusive deals” (Read Staff Post)
I'm actually very fond of Steam, especially since they added the refund for games which don't work properly (I lost plenty of money on games which I couldn't get working). On one of the PC games I worked on I was instrumental in the game leaning heavily on Steam Workshop and other community features.
I'm mostly fond of competition and market disruption. I use a Kindle to read books but I wish there were a viable competitor for buying and reading ebooks.
