Apple recently posted an iPod Game FAQ to answer all your frequently asked (and not so frequently asked) questions about the iPod and its games. As you probably already knew, you need a 5G iPod or later to take advantage of the $4.99 games. You cannot, however, output the video to your TV as you play. And you can use localized game versions--change the iPod's language and the games will relocalize to that language. I hadn't realized that Vortex and Texas Hold'em were Apple in-house products. The rest (like Zuma, Tetris, and so on) are authored and supported by third-party companies.
