Submission + - 2D Game Development Made Easy (sourceforge.net)
BlueMonk writes: "After 2 years of development and testing, version 2 of the Scrolling Game Development Kit, rewritten from the ground up in C#, has been released. The program is an IDE to assist newcomers and experienced developers to relatively easily create resources and assemble them into functional scrolling games based on DirectX. The new version is highly customizable in that almost all the runtime code is embedded in the project data file and can be edited and saved with the project. No runtime other than .NET and DirectX is required to play the compiled games."
