This may be a little late in coming, but recently we discovered that it is possible to install games on both the 30GB Zunes and the newer models (both the 80GB and the Flash versions). ZuneBoards.com has a great tutorial available that shows both how to install the games and where to get some good ones. If you have any success list below in the comments and let us know. I’m a little too nervous to try it myself
