Hello, I'm working on digital distribution platform, something like Steam, or Desura etc. I'm planning to create platform that is simply to integrate with your game. There will be few modules available, like authenticating games and DLC's, achievments including time achievments, updating your game, friends and messages (for example player will be able to invite other player to game, for you it's only few lines of code to add to your project), selling games and DLC's, open and closed beta, etc.
Developer will have a SDK and a devtool for uploading updates, creating achievments and many more. But I have one very important question for you. Would you be interested in using it? As a gamer or developer?
