This section provides tools, guidance, and philosophy for running Worldlines. This is not a rigid instruction manual—it's a resource library for creating the kind of game your table wants to play.

19.1 Core Principles for Game Architects

The Galaxy Doesn't Care

What This Means:

  • Encounters are not balanced by default
  • Players can stumble into situations they cannot win
  • Retreat and negotiation are valid (sometimes only) solutions
  • Consequences persist—killing the wrong person creates enemies, destroying faction property triggers retaliation

How to Implement:

  • Don't scale every encounter to party level
  • Present situations with natural logic, not game balance
  • Allow players to gather intelligence before committing
  • Make fleeing or talking viable strategies

Scarcity Creates Tension

What This Means:

  • Credits are limited, expenses constant
  • Equipment wears out and breaks
  • Ammunition matters, fuel costs stack up
  • Choices between needs create drama

How to Implement:

  • Track maintenance costs and downtime expenses
  • Make equipment degradation visible and consequential
  • Present missions with clear rewards but real costs
  • Force trade-offs between safety and profit

Actions Have Weight

What This Means:

  • NPCs remember how players treated them
  • Factions track standing and respond accordingly
  • Legal consequences accumulate across sessions
  • Betrayals create permanent enemies

How to Implement:

  • Keep notes on significant NPC interactions
  • Update faction standing regularly
  • Let Heat accumulate naturally from criminal activity
  • Show consequences in later sessions (bounty hunters, denied services, faction retaliation)

Mystery Invites Engagement

What This Means:

  • Not everything needs explanation
  • Unanswered questions drive curiosity
  • Temporal anomalies, Qintari motives, Drildec disappearance—these are features, not bugs
  • Players create their own theories and investment

How to Implement:

  • Drop hints without immediate payoff
  • Create multiple possible explanations
  • Let some questions remain unanswered
  • Build on player theories when interesting

19.2 Running Combat

Before Combat Starts

Establish Stakes:

  • What happens if players lose?
  • What happens if they flee?
  • Can they negotiate instead?

Set the Scene:

  • Describe environment, cover, hazards
  • Note enemy positions and numbers
  • Indicate escape routes if any
  • Mention environmental advantages/disadvantages

Clarify Objectives:

  • Enemies may not fight to death
  • Players don't need to eliminate all opposition
  • Tactical victory (securing objective, escaping) counts as success

During Combat

Track Resources:

  • Energy expenditure per turn
  • Ammunition consumption (if tracking)
  • Equipment wear from intensive use
  • Environmental hazard accumulation

Maintain Tension:

  • Enemies retreat when logical
  • Reinforcements arrive if plausible
  • Environmental hazards activate
  • Time pressure increases (alarm countdown, approaching patrols)

Use Momentum:

  • Winning team coordinates actions
  • Enemy tactics reflect intelligence and training
  • Undisciplined enemies act chaotically
  • Professional forces use cover and suppression

Status Effect Application:

  • Don't forget to apply ongoing effects (Bleeding, Exhausted)
  • Track status effect durations
  • Allow recovery attempts as appropriate
  • Describe effects narratively ("The wound keeps bleeding—you're getting lightheaded")

After Combat

Immediate Aftermath:

  • Allow First Aid and stabilization
  • Quick salvage/looting (time-limited)
  • Assess equipment damage
  • Check for pursuit or reinforcements

Short-Term Consequences:

  • Apply exhaustion if combat was prolonged
  • Note equipment wear
  • Track ammunition expended
  • Injuries requiring medical attention

Long-Term Consequences:

  • Heat increase if authorities involved
  • Faction standing changes
  • Witnesses and recordings create complications
  • Dead enemies have friends, families, organizations

19.3 Encounter Design

Designing Balanced Encounters

Use Combat Rating (CR):

  • Calculate party CR: sum individual member CR
  • Design encounters with total CR within 50-150% of party CR
  • Below 50%: Easy victory, possibly boring
  • 50-100%: Challenging but winnable
  • 100-150%: Dangerous, requires tactics
  • Above 150%: Overwhelming, retreat likely necessary

How to calculate combat rating:

Consider Tactical Elements:

  • Cover availability: Alters difficulty significantly
  • Enemy equipment: Armor and weapons matter more than numbers
  • Environmental hazards: Add complexity without adding enemies
  • Escape routes: Presence changes player decision-making

Designing Unbalanced Encounters

When to Use:

  • Demonstrate faction power
  • Create memorable "oh shit" moments
  • Force creative problem-solving
  • Teach players that fighting isn't always the answer

How to Telegraph:

  • NPCs warn of danger
  • Environmental clues (security cameras, heavy armor)
  • Initial contact demonstrates superiority
  • Give players information to make informed retreat

Example Overwhelm Scenarios:

  • Elite military patrol (CR 200% party)
  • Entire gang responds to territory violation (CR 300% party)
  • Corporate response team with air support (CR 400%+ party)

Non-Combat Encounters

Social Conflicts:

  • Use opposed skill checks
  • Multiple successes needed for complex negotiations
  • Failure creates complications, not instant failure
  • Allow players to spend resources (bribes, favors) for advantages

Exploration Challenges:

  • Environmental hazards require skill checks
  • Navigation errors create complications
  • Resource management matters
  • Discovery rewards careful investigation

Investigation Scenarios:

  • Clues don't require rolls to find, rolls provide context
  • Multiple paths to same information
  • Dead ends exist, require different approaches
  • Time pressure adds tension

19.4 Creating NPCs

Quick NPC Generation

Level 1 Template:

  • 2 skills at +2
  • One signature technique
  • Basic equipment appropriate to role
  • Simple motivation

Scaling NPCs:

  • Add +1 to relevant skills per level
  • Add technique every 2 levels
  • Increase equipment quality
  • Deepen motivations and connections

NPC Personality Framework

One-Sentence Description: Examples:

  • "Burned-out cop who still believes in justice"
  • "Ambitious merchant who sees everyone as transaction"
  • "Idealistic revolutionary hiding deep pragmatism"

One Quirk:

  • Nervous tic
  • Unusual speech pattern
  • Distinctive appearance element
  • Habitual behavior

One Connection:

  • Relation to faction
  • Tie to location
  • History with player or other NPC
  • Obligation or debt

Memorable NPCs

Create Investment:

  • Give them personality beyond function
  • React consistently to player actions
  • Remember previous interactions
  • Have goals independent of players

Show Don't Tell:

  • Demonstrate personality through action
  • Let speech patterns reveal background
  • Use body language and reactions
  • Make them flawed and human (or alien-but-relatable)

19.5 Faction Management

Tracking Faction Standing

Record Key Events:

  • Mission successes/failures
  • Betrayals or assistance
  • Resource contributions
  • Ideological alignment demonstrations

Update Standing Regularly:

  • After major missions: ±10 to ±20
  • After minor interactions: ±2 to ±5
  • Decay over neglect: -1 per extended period
  • Betrayals: -20 to -50

Communicate Changes:

  • NPCs mention reputation shifts
  • Services become available/restricted
  • Prices change
  • New opportunities appear

Using Factions in Play

Create Competing Interests:

  • Mission offered by multiple factions
  • Helping one damages standing with rival
  • Force meaningful choices

Show Faction Personality:

  • Different communication styles
  • Varied mission types
  • Unique rewards and penalties
  • Distinct operational methods

Make Consequences Visible:

  • Denied docking due to low standing
  • Bounty hunters deployed by hostile faction
  • Friendly faction provides emergency assistance
  • Rival factions interfere with each other

19.6 Running Downtime

Pacing Downtime

Between Missions:

  • Allow 1-2 cycles minimum
  • More for complex crafting or training
  • Less if time pressure in narrative

During Long Travel:

  • Ship transit becomes downtime
  • Allow training, crafting, rest simultaneously
  • Introduce complications occasionally

Campaign Breaks:

  • Extended downtime (multiple cycles or interludes)
  • Handle major character changes
  • Advance calendar significantly

Downtime Activities

Approve or Adjust:

  • Not all activities available everywhere
  • Costs may vary by location
  • Time requirements flexible for story needs

Introduce Complications:

  • Use random event tables sparingly
  • Create complications from previous actions
  • Tie events to ongoing storylines

Advance Plots:

  • NPCs pursue their goals during downtime
  • Factions make moves
  • Galaxy doesn't pause for players

19.7 Handling Common Situations

Player Death

When It Happens:

  • Allow final moments
  • Give opportunity for last words or actions
  • Make death meaningful, not random

After Death:

  • Allow consciousness backup recovery if established
  • New character can be introduced naturally
  • Deceased character's connections become plot hooks

Split Parties

Managing Multiple Groups:

  • Cut between groups at tension points
  • Don't let one group dominate session time
  • Create situations that encourage reunion

When to Allow:

  • Multiple objectives in same location
  • Stealth missions with backup team
  • Parallel investigations

When to Discourage:

  • Extended separate story arcs
  • Leaving one group with nothing to do
  • Creating GA burden tracking two campaigns

Rules Disputes

In the Moment:

  • Make quick ruling to keep game moving
  • Note dispute for later research
  • Favor player interpretation if ambiguous

Between Sessions:

  • Research official rules
  • Discuss with players
  • Establish table ruling going forward
  • Document house rules

Pacing Issues

Combat Too Slow:

  • Pre-roll NPC attacks
  • Group similar enemies
  • Use average damage for minions
  • Cut minor enemies from scene

Downtime Too Detailed:

  • Handle routine activities narratively
  • Only roll for interesting outcomes
  • Montage extended periods
  • Focus on character moments, not logistics

19.8 Creating Campaigns

Campaign Frameworks

Mission-Based (Episodic):

  • Self-contained jobs each session
  • Easy entry/exit for players
  • Less narrative continuity required
  • Good for casual play

Faction Conflict (Political):

  • Players navigate faction relationships
  • Missions impact larger conflicts
  • Strong continuity between sessions
  • Diplomatic and combat elements

Mystery Investigation (Story-Driven):

  • Central mystery unfolds over campaign
  • Clues and revelations pace story
  • Heavy narrative focus
  • Requires player engagement

Exploration (Sandbox):

  • Players choose destinations and objectives
  • Open-ended with minimal railroad
  • High GA prep for multiple possibilities
  • Strong sense of player agency

Story Arcs

Arc Structure:

  1. Introduction (establish stakes)
  2. Rising Action (complications increase)
  3. Climax (confrontation or revelation)
  4. Resolution (consequences and aftermath)
  5. Transition (lead into next arc)

Arc Length:

  • Short Arc: 2-4 sessions
  • Medium Arc: 5-8 sessions
  • Long Arc: 9-15 sessions
  • Campaign Arc: 20+ sessions

Plot Hooks and Threads

Create Multiple Threads:

  • Personal character goals
  • Faction conflicts
  • Galactic mysteries
  • Immediate survival needs

Weave Threads Together:

  • Character goal relates to faction conflict
  • Immediate mission reveals larger mystery
  • Survival need creates faction involvement

Allow Player Direction:

  • Multiple threads mean player choice matters
  • Not following one thread doesn't break campaign
  • Unused threads can return later

19.9 Worldlines-Specific Guidance

Using Temporal Elements

When to Include:

  • Sparingly—temporal weirdness loses impact through overuse
  • Major story beats or reveals
  • LineSeer-focused missions
  • Late campaign mysteries

How to Present:

  • Clear but strange
  • Consequences visible
  • Player choices matter
  • Not just "it was all a dream"

Managing Technology

Keep It Grounded:

  • Technology solves problems but creates new ones
  • Equipment breaks, requires maintenance
  • Nothing is perfect or magical
  • Scarcity drives economy

When Players Innovate:

  • Reward creative use of existing tech
  • Allow modifications within reason
  • New inventions possible but expensive
  • Balance innovation against game economy

Handling Mortality

Death Should Feel Earned:

  • Warn of danger through fiction
  • Allow tactical mistakes to matter
  • Let desperate gambles be desperate
  • Don't kill arbitrarily

But Death Should Be Possible:

  • Stakes feel real when death is possible
  • Extreme situations have extreme consequences
  • Don't pull punches too much
  • Let players feel the weight of survival
