I eventually got so obsessed with gaming that I got too picky for even my favorite games. I was getting into the martial arts, and wanted a better combat system. I calculated kinetic energies and penetration values for every weapon under the sun. I actually considered using Bio-One, which was a 1974 TSR release that allowed one to identify the particular internal organs and structures affected by gun shots. It was far too complex, so I gave up on that (although I think I still have a 1d1000 hit location roll chart around here somewhere)! I also really wanted to create a whole new magic system, because I wasn’t satisfied with anything I’d found. So around 1984, I created my own system, and we’ve been playing it ever since. Journeyman is the name of it. It’s still unpublished, so you won’t find it anywhere. If you’re an aspiring game illustrator, please drop me a line! The game is a skill-based system where characters often take both magic and fighting skills. I was trying to make a world where Elric of Melnibone and the Gray Mouser would feel comfortable. I think they would be.
That’s what I do as a referee. As a player, I’m in a Pathfinder group. It’s a voluminous system and has the same issues as D&D, but it’s fun and the web support is great! Check out their page at Pathfinder SRD.
