License Change

We've decided to change the terms of the project's license. In lieu of Xamarin blatant copy and commercialization of our project, we are no longer going to allow the MIT license. You can find our license at the GitHub repository. A copy of it follows. Suffice it to say that you can still make games with the framework, and you can do so without paying us anything. You just can't make a commercial product out of this library and resell it as your own.

We intend to protect the work and time that everyone has put into this project to make it free. If you change the framework then you need to push those changes back to us. That's the only price we ask.

This project would not exist if not for Ricardo Quesado, Zhe Hueng, other cocos2d developers, Jacob Anderson, and Gena Minchuk. Together we brought cocos2d to XNA and across 95% of all game computing platforms world-wide.

We are thankful for all of the contributors to the project. Without you we would be overworked even more than now. Thank you for your contributions.

Here is the license now:
