Trail Mix
A downloadable game
TRAIL MIX is a set of backcountry navigation mechanics for TTRPG hexcrawl adventures. The rules are designed to evoke wilderness travel with unfamiliar trails, off-trail movement, bushwhacking, and tracking/pursuit. The tools are designed for solo play, but work equally well for GM-led games. TRAIL MIX is setting- and system-agnostic; most play testing has been with OSR fantasy systems (i.e. Basic Fantasy, Cairn 1e, Knave 1e, Shadowdark), but is designed to be applicable to nearly any system and any setting where wilderness travel is a relevant feature.
- Navigation: You know where you want to go, but the landscape might have something to say about that. "Lost" is a state of mind. The mechanics are meant to evoke the feeling of setting out on a trail over rough terrain, with the hopes (but no guarantee) that it will get you where you're going.
- Travel routes: nebulous trails, waterways, and off-trail overland travel.
- Bushwhacking: thrashing through dense brush, water crossings, scrambling; the landscape doesn't care about your comfort and safety.
- Encounters: open-ended encounters built on two-dimensions: banality/exoticism and temporal context. Populate with foes and creatures from the system of your choice.
- Tracking and pursuit: Chases are not always a sprint. Cruising subalpine meadows is a lot less enjoyable when you see a bear walking the same path, a couple km behind you. And it's the same bear that you spotted behind you three days earlier.

oh shit this rules too!
Been really enjoying this little ruleset. Quick to run once you get the hang of it. The navigation procedures feels a lot more realistic than other hexcrawl rules I've run. Will have to check out your other pamphlets.
One question though, is step 6 missing?
Thanks- I'm glad you're enjoying it. Out of curiosity, which system(s) are you using it with?
Step 6: Oops! The missing Step 6 is an artifact of when I scrapped the "Navigation Point" mechanic in v0.20, which was then step 3; I seem to have forgotten to backfill each subsequent step. Now corrected and v0.22 re-uploaded. Thanks for catching that!
I'm running it with OSE. I used your Hinterland tools to generate the rough map, and then the party navigates with Trail Mix rules. For encounters, when I roll a creature on the Encounters step, I then switch over to the OSE encounter tables to decide exactly what was encountered. Its running pretty smoothly at the moment.
That's great- I haven't tried OSE, but I expect it's similar enough to BFRPG that my test rounds were pretty close. I'm glad it's going well. I've got some more detailed encounter building stuff coming soon, so hopefully that will add a bit more to the experience as well. Also mechanisms for climbing and caving.
