I found a great game that works beautifully on the Netbook Pro. It's a strategy game called "Warring Nations". The game has great graphics and runs full screen. The gameplay is awesome, too. Check it out:

Make sure you download the Pocket PC VGA version. The game runs without any modifications the only thing you have to have is GAPI installed.
