In the world of science, DNA is a recent discovery. In the world of gaming development, XNA is even newer. Simply put XNA is an easy to sue software suite. It lets you make games for both the PC and the Xbox 360. First announced as an initiative at the Game Developers Conference in 2004, the project was led by J Allard. By the end of 2005, the proof of the concept was up and running. At the 2006 GDC, Microsoft released the completed XNA framework.
