How to get started with game programming on the Zune

My zune just updated to 3.0 (didn't even realize they were releasing something new!) and the update came with two games, but the Zune marketplace does not have games.

Where do I go to get started, and what are the capabilities of the Zune in terms of games/apps?

Well, first, you must download the Microsoft XNA 3.0 CTP. Read the documentation, which will explain the capabilities. But, from memory:

• No hardware accelerated 3d (obviously, you can create a software 3d engine and then render the result to a 2d sprite, but... Don't expect much in terms of performance ;))
• No XACT, you must use a new sound API
