Ryuutama Inventory Sheet

Ryuutama tracks inventory with a combination of slots and containers, and it can sometimes be tricky to figure out exactly how much you can carry. Here’s a sheet to help you visualize it.

The left column counts your actual carrying capacity. Use the right columns to show the space you get from containers. e.g. a Large Backpack takes up 5 carrying capacity, but gives you 10 slots, so block out 5 rows and extend them two columns wide to get a total of 10 slots.

Draw Fortress

My entry for the 2016 Game Chef competition is called Draw Fortress. It’s like The Quiet Year crossed with a tower defense game after reading too much Bruce Schneier.

Ingredients: Alarm, Sketch

The combination of “Technology” as a Theme and “Alarm” as an ingredient made me think about security. Security is always about trade-offs. Nobody has the resources to protect against everything all the time, so you have to choose what’s most likely. Any user of the system is a potential weak point, but users are why the system exists. While the initial inspiration was computer security, physical systems are much easier to brainstorm and represent.

Despite a busy schedule, I was lucky enough to playtest the game twice during the week, leading me to cut some needlessly complicated rules and streamline the turn flow. Thanks to my playtesters A. U., D. K., E. G., and T. N.

*After the Game Chef deadline, I added a CC-BY badge to the PDF and fixed a typo in the rules.

You seem like ordinary teenagers, but together you are SUPER PLANET FORCE!

Choose a unique Robot Part to pilot: Head, Right Arm, Left Arm, Body, Legs. Draw your Robot!

When piloting or acting like your Part, roll 6d6; otherwise roll 2d6. Every 5+ is a success.

  • Left Arm – Underhanded, subtle
  • Body – Courageous, resistance
  • Legs – Fast, graceful

The episode starts with a mundane issue: bullies, classes, dating, family, friendship.

Then a (Lightning | Fiery | Icy | Poisonous | Cyber) (Dinosaur | Spider | Moth | Ape | Blob) attacks! Describe how you secretly change into SUPER PLANET FORCE.

Take turns describing the monster’s rampage, then attacking it. Successes charge its Rage Pool. At [Players x3], it transforms and doubles the Rage Pool!

Describe your transformation into TECHNO PLANET WARRIOR!

Together you have [Players x6]d6. Choose one Part to act with all dice in their style. Every success destroys a Rage die. If it’s out of Rage, finish with your HYPER PLANET BEAM!

Describe how the mundane issue is resolved or worsened by the outcome.
