I'm thinking very seriously about self-publishing an old school fantasy product that'd be compatible with OD&D and AD&D. I'm not sure whether I'll even bother with explicitly connecting it to OSRIC or Labyrinth Lord or any of the other retro-clones, because I'm not at all certain it'd make a whit of difference. That's not intended as a knock against either of those retro-clones, which I happen to like a great deal; it's more a comment on the state of the market for old school games right now.
The problem I'm having as I think about this, though, is that I'm not quite sure what I ought to produce. One of the fascinating things about old school games is that, with a few noteworthy exceptions, they didn't really have supplements. The vast majority of their products were adventures -- why that is I plan to use as the basis for an upcoming post -- but the market is already pretty crowded with old school adventures and I'm not a name like Rob Kuntz, so I'm not sure how much attention I could garner. On the other hand, I have a couple of ideas, one being a full-tilt pulp fantasy adventure to lay the groundwork for my pulp fantasy D&D project. The other idea would be an old school "adventure path," basically a series of loosely connected adventures that do for old school gaming what Paizo has done for the newfangled stuff. More to the point, I think a lot of gamers don't have a good sense of how an old school campaign was structured and a series of adventures would nicely illustrate its differences from more contemporary models.
I have some other ideas too, but I'm still not sure which way to go. Mostly, I want to put my money where my mouth is and see if I can produce something whose production values and presentation are attractive and modern but whose content doesn't just feel old school but in fact is old school. I truly think there's a market for this stuff, a market far bigger than the make-it-look-like-TSR-circa-1981 stuff that strikes me as what Jeff Rients has called "symptomatic of stodginess."
Old school gaming isn't stodgy and shouldn't be stodgy. I think I can prove that, but I need the right product to do it. So, suggestions please! If you were to give me an assignment to create the ultimate new old school product, what would it be? What would you want to buy? What do you think would attract the most gamers who might otherwise never give an old school product a chance?
