Really, the GoW ones are to teach you PyPRP-specific things for the most part. Even though the wiki says:
Learn Blender either through the Blender Noob to Pro tutorials, or the GoW Tutorials, which focus on Age building.
...this isn't the case. It's very hard to write tutorials when you can't assume someone already has been taught something. It gets very complex, this is an example:
First version: "First, start by making a UVSphere with the segments and rings both set to 20." Me: I need to make this easier.
Revision 1: "First, start by pressing the space-bar or SHIFT-A in the 3d-window to pop up menu. Click the UVSphere item in the menu that popped up (Add->Mesh->UVSphere). After that pops up set the "Segments" to 20 by clicking the "<" arrow in the dialog. Now you need to set the "Rings" to 20. Follow the same procedure as you did for setting the "Segments"." Me: Still this could be difficult for someone who hasn't started Blender yet.
Revision 2: "First, start Blender (you should follow your OperatingSystem's program-starting protocols, for Windows double-click on the Blender Icon on your desktop, for Linux using Gnome navigate though the menus until your find it, then single-click on release the mouse button to launch it). If you do not have Blender you'll need to choose the right version for your machine. [omitted long instructions telling how to find, download, and install Blender] Now, start up Blender. You should be greeted by a splashscreeen. This varies depending on your version. The big gridded screen in the middle is the 3d-window. [omitted some stuff] Now, press the space-bar or SHIFT-A in the 3d-window to pop up menu. Click the UVSphere item in the menu that popped up (Add->Mesh->UVSphere). After that pops up set the "Segments" to 20 by clicking the "<" arrow in the dialog. Now you need to set the "Rings" to 20. Follow the same procedure as you did for setting the "Segments".
I'm not trying to make fun of the new people here by saying they need tutorials written like Revision 2 but if I were new this is what I'd want. I think reasonably there's only one place to start with learning to make ages and that's a simple tutorial about Blender itself. This way, tutorials don't have to repeat everything again and can be written faster. This sample tutorial is about how my tutorial-writing goes. It's just I usually never get the completeness that's shown in even Revision 1

.
I'm going to do some wiki changing to try the fix the notion that the GoWs can provide everything you need ('cause it can't).
Currently getting some ink on my hands over at the Guild Of Ink-Makers (PyPRP2).
