The_Prophet, this sounds like an excellent venture. Please do consider making this tutorial on RPG's. Also, consider doing a similar format to the ones Kinji has done. One basic concept, followed by expansion on the main idea. That way you could easily develop a complex combat system, or even a campaign engine to the mix over time.

BasketBallBen seems to be offering to help. Maybe you will want to do a battle engine tutorial later? I'd be considering scooping up whatever support came my way! If not, BBB, why not do one anyway! Collaborative efforts are great, but the innately curious will learn from wherever we can get our knowledge...

Just my 2¢
