Before In Her Majesty's Name I had been writing and publishing a range of wargames and roleplaying games rules for several years. Some were to disappear without trace in all the hurly-burly but several really did quite well.
Over those years I set up a couple of blogs dedicated to these games:
The first was The Games Shed, also known as Gawd 'Elp Us Games. This mostly hosted my wargames rules including Forge of War and the FUBAR series of one page wargames rules. This became pretty successful with thousands of downloads and soon I had a metric tonne of contributors and collaborators, all of whom are credited in the various rule sets they helped develop.
http://thegamesshed.wordpress.com/The second, Dead Simple RPG, is a blog dedicated to my Dead Simple, one page roleplaying games system. With over a dozen genres covered it has had many thousands of downloads. I'm currently running the Blaster! SF RPG with my local games group, so it is alive and kicking.
http://deadsimplerpg.wordpress.com/The last blog is not mine. As some of you may know, the forerunner to IHMN was ItEN or In the Emperor's Name. This was a set of W40K skirmish rules that filled a niche GW were basically ignoring and was pretty successful. So much so it went into a second edition before Osprey came across it and offered me the opportunity to write IHMN.
After that I did not have time to further develop it so my friend Gavin stepped in and became the Editor-in-chief for the third edition. You can find his work here:
