Hacking Roleplaying Games for Fun and Profit


When people refer to modding games, the term tends to refer to modifying video games (or, at least, hardware and software in general). Modding is a weird situation for designers, in that you’re getting a preexisting design, and you’re hacking and slashing and adding to it to match a new design. It’s as if you were a sculptor, and instead of getting a fresh block of marble, you’re given someone else’s sculpture.

However, what a lot of people don’t know is that there is a fairly vibrant culture of tabletop RPG hacking out there, of people taking tabletop RPG systems and modifying the rules for new purposes. For instance, check out this hack of Fantasy Flight’s Edge of the Empire system, turning the system into a sword-and-sorcery fantasy game. Or, alternatively, you can play some Star Wars, but with this hack of Apocalypse World.

Not wanting to be left out of the fun, I’ve decided that, as long as I have a bit of free time between semesters, I’m going to try my hands at a bit of hacking, just for fun. After all, it’ll take less time than starting a new game from scratch (especially considering I have in progress projects that need time), while still scratching the itch to work on something new, as well as getting some time to bang around in someone else’s rules and maybe see how an actual pro does it.

The system I’ll be hacking is Dungeons and Dragons, 4th Edition. I’ve read through the 4E rules, and am very familiar with D&D rules in general, but always disliked using miniature combat in general, and my affection for 3.5/Pathfinder was too great to be shook by a new edition (at least, until friends from my gaming group ranted and raved about 5th Edition).


Now, inspired by some reddit posts of other people who’ve taken to hacking Fourth Edition, I’m going to take a crack at it myself. Hopefully, this project won’t consume too terribly much time (when compared to a full game designed from scratch), and should be pretty fun.

Step one to this process is rereading the rules for Fourth Edition. Taking a deep dive into how the actual game functions, and reading them with hacking in mind, is an obvious first step. See what I don’t like, see what I do, and generally try to piece together what the rules are lending themselves to, what situations the rules seem built to push sessions to, and what mood the rules evoke.

With that knowledge in tow, the next step is to figure out a plan. I think it’s safe to say that I don’t want to keep the setting wholesale, since I already have a perfectly good game for playing D&D, and that’s D&D. Whether that means I’ll turn it into some other type of fantasy (perhaps some Warhammer-style grimdark, or something a bit more cutthroat and in the shadows), or maybe I’ll turn it into something completely different.

Given that the rules set I’ll be working with is D&D, the third step will most likely be the construction of classes. 4th Edition is very class-focused, giving each class unique paths and abilities, so redefining those classes will be the easiest way to make significant changes to the game. Classes define what the major roles players can take on will be, what players will be doing, and what sort of stories the game will facilitate.

With that, the fourth, and biggest step, is to go at the rules themselves, and make the changes as I see fit to match the vision. I don’t 100% know to what extent these changes will be made, since I don’t know what they are yet, but the more extreme the setting change, the greater the mechanical changes will be, more than likely, although I don’t want to get too far away from the original rules. Generally thinking, I believe my policy will be to try and keep everything that I can, and making minimum possible modifications to the actual rules, only changing what I need to.

Once that’s done, the “last” step is to playtest. The reason I say “last” is that playtesting and modification of the rules will probably go hand in hand, with multiple repetitions of each in a cyclical fashion, as playtesting informs rules modifications and rules modifications demand playtesting.

I think modifying tabletop RPGs is a really interesting idea, and very easy to do. After all, all you need is a word processor. With this project, I’m looking forward to the idea of taking an established game and making it something new.
