Is there any cheat sheet for BGE, I was unable to find it. Thanks. 
What exactly do you want to see in this “cheat sheet”?
Basic diagrams of how BGE works to get the picture http://i.cmpnet.com/ddj/ddj/images/ddj9718k/9718kfig1.gif . How is it connected to blender models, their properties, what event handlers are there …
