An article that I find great, has appeared in HardyDev. Derrick Freehand an ags forum member, being on the working of his game Collision, has written an article about how one should create his game world. It mostly scratches the surface, but that doesn't mean it doesn't have valid information. I feel its really worth checking out. Here's the topic of Collision and here's a link for the article.
Also on a side-note the first MAGS under the hosting of Atelier is over. See the results, here.
