RedBlue if you are looking for more of an academic experience I would recommend Coursera's Game Design and Development Specialization. These courses provide structure and deadlines and they also have message boards where your cohort can interact. The specializations uses Unity as a platform and the curriculum was developed by Michigan State University. These courses run about 50 dollars a class and there are 5 classes to complete the specialization. I haven't taken this particular set of courses yet, but I did take the University of Colorado's XNA C# course on Coursera and found it to be quite good. Here is a link to the specialization Click Here
Alternatively, if the cost or format of the MSU course doesn't seem like your flavor. I would recommend using this board and unity3d beginners boards (or UDK depending on your preference). There are many beginners here looking to make progress towards their Indy and professional game development dreams. This is an ideal recruiting ground for other eager learners and all important mentors. It maybe fully possible to get a group of 5 - 10 beginners together who are eager to learn. You could setup your own Sharepoint or other collaborative space. I recommend Asana for robust FREE collaborative project management tools.
Once you have your eager 5 - 10 active participants. You will need a mentor to help you guys develop a curriculum. This may involve contacting Unity maybe they have some guidance they can provide. Maybe this can be be senior member of this board who is willing to take time to help you guys develop periodic tasks and milestones.
I know this post paints the picture in broad strokes, but we can flesh this out as time goes. I am currently working full time as a firmware developer and going to school full time, but if you can't tell I would love to participate.
