The design intent for the combat mechanics in Romance of the Seven Worlds is to have a quick process that produces outcomes similar to the comics and movies. In particular, combat can lead to units changing sides, or duels between opposing commanders. It is expressly not intended to produce realistic combat outcomes, or to require much in the way of logistics beyond spending fuel to move places.
One of the key factors in the combat system is a desire to limit the number of combat units each player can control. Most players will start the game with no more than one or two combat units, and have a maximum of three to five units that they can command. By limiting the number of units each player controls, we can have each individual unit be rich in information about its capabilities.
Each cube counts as one strength point. Yellow cubes are tech cubes, and count as a strength point for tech battles, when all other cubes are worth zero strength. The other colours used for strength cubes determine the faction loyalty that group of people support:
- Black: support the Emperor;
- White: support the Rebels;
- Blue: support the Nobles;
- Orange: support the Guilds.
So the unit pictured above has a strength of seven in Attrition battles, three in Tech battles, and one to two in Sway battles. Note that loyalty cubes may also be important for Pulp Actions targeted at the unit. The above unit is more likely to be sabotaged by the Rebels than anyone else. In Tactics and Chance battles it has a strength of zero.
This is a player versus environment (PVE) combat mechanic. Each game turn Control will pawn a number of meteor swarms in up to five of the zones on the Space Map. Players who control Rocket units can then choose to intercept the meteors and try to destroy them. This costs a fuel token, and you can only intercept meteors in one space zone each game turn.
This is a simple process, where the player rolls 2d6, adds unit strength, and if this is equal or greater than that meteor’s fixed strength rating, then the meteor is destroyed. If the roll is equal or less, then the Rocket takes one hit, reducing its strength. You can keep trying to shoot a meteor down as long as you have time left left in the Warlord Phase, and strength left in your Rocket.
Any meteors not shot down strike the planet in their space zone, damaging bases and units there. This is a bad thing, and players should work together to stop this.
This is a player versus player (PVP) combat mechanic. The usual trigger is a player moving units to a region controlled by another player, and declaring an attack. If in doubt, Control will determine if a battle happens.
First, any of the players involved in the battle draws a battle card. There are seven types of battle card:
- Cliffhanger: place a one minute sand timer down, when it runs out draw another battle card. If the Warlord Phase ends before the battle is resolved, then all the units involved in the battle are locked in combat until the next Warlord Phase (you could use a Pulp Action to escape the situation). For each Cliffhanger card draw, all players in the battle add 1d6 to the dice they roll.
- Romance: place a one minute sand timer down, players involved in the battle may court each other using the Romance mechanic. Unexpected alliances and betrayals may occur. Otherwise treat as a Cliffhanger.
- Attrition: roll 2d6 + Strength.
- Chance: roll 2d6. Do not count strength cubes at all for battles resolved by chance.
- Sway: roll 2d6 + Loyalty + character Charisma. You only count strength cubes that have loyalty matching your declared faction – this includes cubes on units controlled by other players!
- Tactics: roll 2d6 + character Tactics.
- Tech: roll 2d6 + Tech + character Science.
If for some reason you are unable to roll dice for your units, your side is assumed to roll a 2 when Control calls time at the end of the Warlord Phase. Character attributes only count if the character is present in the region where the battle is fought.
Astute players will have noted that outnumbering a player 10:1 matters not at all if a Chance battle occurs.
In battles, a tied result causes a duel to be fought between opposing commanders (duels may also take place in other parts of the game and use the process outlined here). Duels are 1:1 fights, no ganging up. At the start of the duel, each player announces the stakes they are fighting for:
- Capture: win one duel round to capture your opponent and win the battle;
- Wound: win two duel rounds to wound your opponent and win the battle;
- Kill: win three duel rounds to kill your opponent and win the battle.
To resolve the duel, each player rolls 2d6 and adds their Dueling score. Dueling ties can be won by playing an Inspiration card. Otherwise keep rolling until one player achieves their stake. Note that while a “Death” outcome for a character can be negated with a Pulp Action, the battle will still be lost. If both duelists achieve their stakes in the same round of dice rolls, then both sides are assumed to have lost the battle for casualty purposes, and the defender retains control of the region being fought over.
The player with the highest score wins the battle. If there are multiple players on one side, their scores are not combined together – it is just the highest score that counts.
The winning player gains control of the region where the battle took place (unless it was already controlled by an ally).
Units lose strength cubes based on the type of battle card used to resolve the battle:
- Cliffhanger: as below.
- Romance: if peace broke out between the players, no strength cubes are lost.
- Attrition: each of your units loses strength cubes equal to your foe’s highest die roll (max six cubes).
- Chance: each of your units loses strength cubes equal to your foe’s lowest die roll.
- Sway: winner gains all defeated strength cubes with matching loyalty from enemy units.
- Tactics: no one loses cubes.
- Tech: each of your units loses tech cubes equal to your foe’s lowest die roll (no loss if you have no tech cubes).
If a unit has no strength cubes left, it is destroyed and removed from play. It can be rebuilt later using the normal build action process. Surviving units on the defeated side can disperse and retreat into the local wilderness, or if Rockets are available, retreat to a controlled base on any of the seven worlds.
As various science projects are researched or Pulp Actions implemented, your combat capabilities may change during the game. The core mechanics above will remain, but new bonuses or penalties to the die roll, new battle cards, or different battle card draw process, or casualty process may happen.
