Further to my previous post Games are the Way to Test Software, I wanted to mention the new Office Ribbon Hero game. Score points by using the ribbon, accept challenges and share your results with your Facebook friends.
Can you imagine if you were new to Office how helpful this would be? It makes me think of the XT typing tutor game I played back in high school. It was similar to missile command--words falling down the screen and the player has to type them before they destroy bases. Great game.
