Article: Vacant Skies – Action RPG Tutorial Series
by Aaron T Foley
Welcome to the Vacant Skies – Action RPG Tutorial Series. My name is Aaron Foley and I’ll be your host throughout this series. The primary purpose of the series is to document a route on how to make a complete action RPG using XNA and various resources throughout the internet. There are so many amazing resources out there now for XNA that it is pointless to keep reinventing the wheel when writing a game. So I’m going to collect various tutorials, code, and libraries and utilize them all to create a game. So let’s get this show on the road.
Article: XNA Farseer Platform Physics Tutorial
by Roy Triesscheijn
Today I’m going to introduce you to a neat 2D physics engine for XNA called Farseer. With the help of this 2D physics engine we are going to create a small platform ‘game’ while introducing the important concepts of Farseer like bodies, geometry, joints and springs.
By the end of the tutorial, you'll be able to build something like:
Article: Rolling World Tutorial
by Christian Schlager
When you look around the XBox Indie Games Channel, there aren't a lot of 3D games around. Most XNA games only feature 2D graphics. I hope to contribute with this tutorial to making 3D graphics a bit less intimidating. And maybe the little prototype we will create throughout the next pages will be the starting point of a great 3D indie game by one of you 
We will make a prototype that features the kind of rolling world effect that you can see in games such as Animal Crossing or DeathSpank. We will also create the textures and 3D models that go along with the rolling effect and recreate the combination of 2D art with a 3D world you can see in the game DeathSpank.
Nick Gravelyn’s Alien Aggressors Tutorial
Nick Gravelyn (no introduction needed) has been kind enough to send us his Alien Aggressors tutorial (for XNA Game Studio 2.0) and allow us to share it with the world.
You can get the tutorial here: AlienAggressors.pdf
And you might also need the AlienAggressorsContent.zip pack of content to be used with the tutorial.
P.S. This article first appeared on Ziggyware (now defunct) a while ago.
ASCII post processing
Louis Ingenthron has a new article at Conding4Fun in which he shows us how to write a post processing effect that turns 3D into.... wait for it... ASCII Art.
He goes into great detail about how the effect works and the result is impressive, as seen below.
