Right before bed last night, I had an idea. It may be a dumb one. We'll see.
I've spent the past year or so tinkering with my Treasures, Serpents and Ruins house rules to get them to where I pretty much like them (a few tweaks still needed, as we play with them). And after a lot of effort to combine traditional Western and my preferred Eastern fantasy tropes into one simple set of classes/races, I was struck with the idea that I should make a second edition of Flying Swordsmen that is completely compatible with Chanbara. That way I'll have samurai/ninja action as well as Hong Kong style kung fu/wuxia action in one integrated rule set.
Of course, would it be worth my time to make a completely new game, or just the player facing rules as a supplement to Chanbara? The latter is much easier and more likely to be completed. I added a lot of monsters and spells from FS already into Chanbara, so just adding some rules for martial arts classes Chanbara style might be enough.
