Bungie's Marathon is unique in that it's world, aesthetics, and game mechanics grip different people for different reasons. Many love the aesthetics but can't get behind the gameplay. Many love the shooting and heat, but bounce off of its looks. The lore is hidden under miles of codices that even the most seasoned detective might have a hard time digging through, while others would play an entire game that's *just* the codex.

WELL, this is a game jam for all of us. There is a lot to take from Marathon. A lot to learn. A lot to be inspired by. This jam is about honing in on those things and being as blatant as possible. I've found that only through the most obvious version of an idea can you then strip it back to find what it is about it that belongs solely to you. So we're going to file the serial numbers off of Bungie's latest work and steal from it with our whole chests.

This is the place for:

  • 3D printed OSR clones
  • hacks, rip-off, spin-offs
  • mechanical exploration
  • napkin notes for a game
  • aesthetic exploration
  • lyrical attempts
  • lore dives and world building
  • shitty 4e rip-offs
  • Basically, anything and everything that comes from your love/disdain of Marathon.

This jam runs for the entire month of September. So plan, write, and design your game NOW. TODAY. Nothing needs to be "finished" or "polished." You can join the discord and talk about that stuff and even playtest your vision. But mostly, this is your opportunity to JUST MAKE SOMETHING.
