1. Kodu
“Microsoft Research released a community game cum programming environment for the Xbox 360 called Kodu. Unlike most other video games, Kodu would let players create their own video 
games for the Xbox without any prior knowledge of programming.
The initial version of Kodu required the Xbox 360 console but now Kodu is available as a free download for your Windows PC as well. This means you no longer need an Xbox to design games with Kodu and you can play them on just about any computer using a keyboard and mouse (or an Xbox game controller, if you have one).
