Michael Tumey of the Gamer Printshop is running a Kickstarter to help get printed a tutorial book about making maps. What impressed me was the range of software being targeted including my favorites Inkscape and CorelDRAW. For my friend Tim of Gothridge Manor there looks to be a section on how to use Xara which I know he has.
To me the Old School Renaissance is not about playing a particular set of rules in a particular way, the dungeon crawl. It is about going back to the roots of our hobby and seeing what we could do differently. What avenues were not explored because of the commercial and personal interests of the game designers of the time.
