I was thinking that it might be a good idea to create a basics tutorials for each existing topic. Some of the tutorials that have already been created would fit into it.
Here's a list of what I am thinking so far. The ones that already cover the basics in some way are linked to.
Once we have a tutorial covering the basics of these topics, a basics 'course' could be set up. It'd look like the other tutorials on the site, but instead of actually having all the content, it would simply tell beginners which tutorials to use for each topic. Almost like a table of contents, or similar to a 'course' on Blender Cookie.
Now that I think about it, something like that might be a good idea for the game engine tutorials too. Maybe I can set one up to show exactly what I am talking about, if it doesn't make sense here.
