Nicholas Lovell: In the feedback for How to Publish a Game, one element stood out.
I had suggested that it made sense for a developer making PC games to work hard to get on all the distribution platforms. Not just Steam, but GamersGate, Metaboli, Direct2Drive and so on.
Bollocks came the resounding response.
No-one wanted to be quoted. But Steam seems to account for by far the majority of the revenue of every single company who came back to me. People were suggesting that Steam outsold, by a factor of 10 or more, all of the other sites combined.
