All but one are by 3D Buzz, the folks behind the 'Mastering Unreal Technology' books and the tutorial videos included with the Special Edition of Unreal Tournament 2004.
The UDK offers the Unreal Engine 3 development toolkit--minus engine source code, of course--completely free for noncommercial and educational use, with commercial licenses beginning at a mere $99 followed by a 25% royalty on all revenue over $5,000.
This is awesome and the timing could not be more perfect, as I just started to look for UDK tutorials. I want to prototype (and possibly develop) some non-FPS game pitches in my spare time and so far the hardest thing about the UDK is figuring out how to get started without using the FPS example stuff.
If you don't have alot of coding experience I would recommend using Unity for non-fps games, much easier place to do that sort of thing.
