"After reading the recent article in which Randy Pitchford from Gearbox Software said that he thought Valve was exploiting small developers, I decided to offer some perspective "from the trenches."
As a small independent developer that has released multiple games on Steam, we are exactly the type of studio that Randy believes is being exploited by Valve. Additionally, as president of Tripwire Interactive, I've personally been involved in all of our business deals with Valve and have experienced firsthand how they treat independent developers.
So, is Valve exploiting independent developers? In short: absolutely not. Without pulling any punches, I can say with certainty that if it weren't for Steam, there would be no Tripwire Interactive right now."
