XNA Rockout has been renamed, and the aim of the game has been changed a little bit.
However, I have completed the webcast series. I'll be making some minor adjustments and uploading to MSN Video throughout the day.
I have a blog post loaded up with everything you need to know. For now, just know that this is over 12 webcasts aimed at teaching you how to build a 3D XNA game for PC and Xbox from Scratch using FREE TOOLS. I don't skip steps, and you'll learn how to do it without having to make a forum post every 10 seconds ;)
Keep your eyes out or subscribe to my blog to get the update later today.
