Saga Machine

Saga Machine A roleplaying game of actions and consequences!

Saga Machine is the flexible roleplaying game engine used by our Shadows Over Sol, Against the Dark Yogi, Dime Adventures and Age of Ambition game lines, as well as many of our upcoming games. It’s a rules-medium system with an emphasis on both ease of play and clever character options.

The System

At its heart, Saga Machine consists of eight basic stats and two central mechanics, appropriately called the action mechanic and the consequence mechanic.

From there, the core is supported by numerous subsystems, each tailored to the specific genre and themes of the game in question. For example, Shadows Over Sol comes with both engineering and hacking systems, as befits as science fiction game, while Against the Dark Yogi has a system for channeling cosmic energies and Age of Ambition has systems for both inventing and climbing the social ladder.

The Stats

There are eight central stats in Saga Machine, four physical and four mental. Each stat ranges from 1 to 10, with a 4 or 5 representing human average.  Titanic monsters or demigods can have values reaching as high as to 20. The stats are as follows:

  • Strength (Str): A character’s strength is a measure of her muscle and physical prowess. It helps determine how much she can lift and how hard she can punch.
  • Dexterity (Dex): A character’s dexterity is her coordination, flexibility and balance. It helps determine her athletic ability, aim for attacks and manual dexterity.
  • Speed (Spd): A character’s speed is a measure of how fast she moves, her reflexes, agility, her reaction time and her ability to get out of the way when enemies are trying to stab her.
  • Endurance (End): Endurance is a measure of a character’s toughness, health, constitution and stamina. It helps a character resist disease and keep from getting winded after a long jog.
  • Intelligence (Int): Intelligence is an indicator of how quickly a character learns, how much she knows and what her capability is in terms of logical reasoning and deduction.
  • Perception (Per): A character’s perception is a measure of how alert she is, how good her senses are and how quickly she processes new information.
  • Charisma (Chr): A character’s charisma is her force of personality, presence and bearing. It’s used when trying to make friends, influence others or strike a deal.
  • Determination (Det): Determination is a character’s resolve, mental fortitude and grit. It’s used when resisting fear or other mental effects, and in seeing things through to the bitter end.

In addition to these eight stats, most Saga Machine games feature a skill list, with somewhere in the range of 18 - 25 skills. The individual skills vary with the genre and setting.


The first central system in Saga Machine is the action mechanic. By default this uses a standard deck of poker cards, although an alternative d10-based mechanic is included as an appendix in most games.

The mechanic is simple: Add the character’s stat, plus the value of the card flip, and compare this total to a target number. Higher is better.

When a skill applies, it will provide a modifier to this flip. Additionally, sometimes how much a player succeeded or failed by is important. This is known as the Margin of success or failure.

Every Saga Machine game features some sort of “luck” trait, variously called Karma, Edge, Moxie or Luck, as best fits the genre. This trait determines how many cards the player gets to hold in her hand. Cards can be played from hand to influence actions in different ways. Otherwise, a player making an action may always choose to play from the top of the deck.

All of the numbered cards, ace though 10 (aces are low) are worth the value printed on the card. How face cards - jack, queen and king - are handled depends on the game. In most recent games, they are worth a value based on the character's Luck. Finally, when a joker comes up, the action in question is a critical failure, but the player gets to refresh her hand!

Last but not least, Saga Machine makes use of card suits. In different games, suits may be used to either build flushes or certain actions may have a trump suit that provides a bonus. Card suits may also have other effects, including triggering different combat options or helping to determine damage.


The second central system in Saga Machine is the consequence mechanic. Consequences are Saga Machine's way of representing lasting effects in the system. These effects can be placed on either characters, objects or the scene itself. For example, tripping another character may result in a “prone” consequence for the target, setting a forest on fire results in an “on fire” consequence for that forest, etc.

Consequences come in two parts: an effect and a duration. This tells what the consequence does and how long it lasts, respectively. Consequences may apply modifiers to actions, deal ongoing damage, restrive movement or have other lasting effects.

Tales of countless adventures in Bhurloka await the telling. Befriend the monkey-people, the vanaras. Face down the cruel rakshasa Ravema in his island fortress. Climb Mount Niru and visit the gods themselves. Treat with the naga tribes deep in the underworld, Patala. And much, much more!

Shadows Over Sol is a science fiction horror game, taking place in a hard sci-fi vision of our own solar system.

Two hundred years from now what should be the shining beacon of the future is instead cloaked in conspiracy and horror. Humankind has expanded throughout the solar system, and there discovered mysteries older than humanity. The culture has shattered into myriad subcultures; nation-states are the hollow shells of what they once were. Corporations and other groups wage small-scale wars in the streets or in space. Bioengineered horrors left over from these conflicts stalk the hulls of ruined stations and abandoned colonies. But for an enterprising team willing to brave the horrors, there’s always a profit to be made.
