Pluralsight has released a free game (basically a Diablo Clone) which is geared towards teaching game development. You can download and try the game yourself here. And then log in to your accounts to watch the lessons on how they made the game. It’s great to be able to see the entire game design pipeline in one place. Take advantage of it!
Watch this one video and you will learn all you need to learn to get started with Marvelous Designer.
Daryl Obert works at Autodesk and he posts a video tutorial on youtube most Mondays. I’ve always found them to be a great resource!
