So, let me tell you about my D&D hack.
I put this together for my Castle Xyntillan campaign. After a 30+ session campaign using The Black Hack I decided I wanted to try a ruleset that would be closer in feel to Original D&D. In particular, I had grown weary of the roll-under ability score mechanic. What I did like about TBH, and continue to appreciate, is its simplicity and accessibility. So whatever I would switch to would ideally be of a similar level of complexity.
The obvious choice would have been Swords & Wizardry, because that’s what the megadungeon is ostensibly written for, although I believe Gabor Lux used another system to play-test it, and there are a few details, like intelligent sword stats, that don’t show up anywhere in S&W. But I wanted something a bit more light-weight, while at the same time maintaining full compatibility with the module’s contents.
I also considered using Old-School Essentials, but although its presentation is incredibly slick, believe it or not, I still felt it comes with overhead that I would then have to house-rule out. I wanted to be able to have one document that would contain all of the rules.
So, I decided to put together a full-fledged hack of my own. The trigger, if I recall correctly, was reading the Kazamaták és Kompániák basic classes. I really liked the level 6 ceiling on those. It nicely matches the level range of CX and I prefer a low-level game anyway.
Not feeling like re-inventing the wheel, I looked around for a game to use as a chassis. Ultimately I went with White Box: Fantastic Medieval Adventure Game. It’s small but comprehensive, and therefore makes for easy copy-pasting and adapting.
So those are the two basic building blocks of what is now titled “Hackbut”, my classic D&D rules kit-bash: WBFMAG provides the rules framework, and KéK provides the classes, although I did overwrite quite a bit of both. Other key elements include Delta’s Target 20 for attack rolls, and Homebrew Homunculus’s simple d20 skill system for, well, most all other situations that need resolving through dice.
There is a lot more to be said about the various components that make up Hackbut, but I’ll leave that for future posts. The point here was mainly to say that if you are in the mood for putting together your own D&D hack, consider picking up WBFMAG. It’s an excellent place to start if you want something that is fully compatible with the old editions but easily adaptable.
Update: Read on for the first of three posts on Hackbut’s core mechanics, on attack rolls.
