Vladimir Cole at Joystiq publishes an in-depth "Interview with Chris Early, Studio Manager for Microsoft Casual Games Group."  Definitely worth a read!  From the interview, Chris explains his thoughts about what his studio is all about:

"Our thought is that games at their core are fun, are supposed to be fun. They touch you wherever you are, so we want to make sure that you can play those games wherever you have fun--quickly, wherever you are with whatever device. That's our commitment: to deliver that fun experience to the players but also to do it in such a way that they feel they're part of a larger community, that they feel that there's an attraction and a reason to play the games here at our different sites."
