Had to look that up, but I think just the Kinect Sports stuff. Which is 3 separate games? I refuse to go back to Wikipedia. Lol. Still, the list seems to be made to represent the most recent releases.
But... it doesn't... Kinect Sports should be on there. I know off the top of my head that Ninja Theory did DMC after enslaved and I'm 100% positive that Doublefine has made more than 3 games since the PS2.
