I'm not sure why I was surprised, but the Pixar game (w/Buzz) seems to be running in Classic, with OS X's blue "Apple", and desktop showing behind the game's window.
I guess I incorrectly anticipated that it might only appear via 9.2.2.
It's going to be interesting to see how much real use 8.6 gets, with the several older ed games, used earlier by the next youngest grandchild (now 9) when he visited us.
More glad than ever that I set The Molar up as I did.
