Starfinder is a science fantasy tabletop RPG published by Paizo in 2017, set in the same universe as Pathfinder but 317 years in the future — the Pact Worlds, a solar system of diverse civilizations, space stations, and alien planets. Characters are spacefaring adventurers who travel between worlds, explore derelict ships, navigate interstellar politics, and battle threats ranging from undead starship crews to alien corporations to extraplanar horrors. Mechanically, Starfinder is built on a modernized version of the Pathfinder 1e rules base — familiar to d20 players but updated with a three-action economy (carried forward into Pathfinder 2e), Resolve Points (a per-rest resource pool), and integrated science-fantasy technology including starship combat rules. A Second Edition (2024) brings the game in line with Pathfinder 2e's systems.
How to play
Themes and Classes: Characters choose a Theme (backstory archetype: Ace Pilot, Bounty Hunter, Icon, Mercenary, Outlaw, Priest, Scholar, Spacefarer, Xenoseeker, or Themeless) that provides a bonus skill and Theme Knowledge ability. Classes determine core abilities: Envoy (skill-focused leader), Mechanic (engineer with drone companion or exocortex implant), Mystic (divine spellcaster with a spiritual connection), Operative (agile skill and combat specialist), Solarian (warrior channeling stellar energy into light and gravity), Soldier (combat specialist with fighting styles), and Technomancer (arcane spellcaster who blends magic and technology). Stamina Points and Hit Points: Characters have both Stamina Points (SP) — a buffer that regenerates fully with 10 minutes of rest and 1 Resolve Point — and Hit Points (HP) — which require medical attention or full rest (8 hours + 1 Resolve Point) to recover. This dual-track system makes short-term sustainability (per-encounter recovery) separate from long-term resource management. Resolve Points: Characters have Resolve Points equal to half their level plus their key ability score modifier. Spend to: recover Stamina between encounters (1 RP), stabilize at 0 HP (1 RP), activate certain class abilities. A character at 0 RP cannot recover Stamina and is one step from permanent death. Weapons and Technology: Equipment is divided by Item Level (1–20). Characters should have equipment approximately matching their character level. Weapons deal more damage as Item Level increases. Upgrades and weapon accessories (scopes, stocks, high-capacity magazines) modify function. Armor has both EAC (Energy Armor Class, resists energy weapons) and KAC (Kinetic Armor Class, resists physical weapons) — attackers choose which to target based on weapon type. Starship Combat: A separate sub-system where the party's ship fights other vessels. Roles include Pilot (maneuver the ship), Engineer (repair and boost systems), Gunner (fire weapons), Science Officer (scan and target), and Captain (boost crew morale). Starship combat runs on a different action economy and scale, resolving in rounds of strategic positioning.
Strategy
Starfinder rewards characters who balance their combat effectiveness with the game's significant out-of-combat pillars (exploration, social interaction, technical problem-solving) and who invest in their starship as a party asset. Equipment investment is mandatory: Unlike Pathfinder or D&D where magic items are supplementary, Starfinder's economy is balanced around characters having level-appropriate gear. A character using item-level-5 weapons at character level 10 is dramatically less effective than one using item-level-9 weapons. Prioritize upgrading your primary weapon and armor above all other purchases. Class synergy in the party: Starfinder classes are highly specialized. An Envoy provides crucial action economy through abilities that let allies act more efficiently; a party without an Envoy is significantly less effective. A Mechanic's drone provides an extra "character" worth of actions. Plan party composition before character creation — cover combat, technical/engineering, and at least one socially capable character. Starship combat crew roles: Assign starship roles to each player based on character strengths before your first space encounter. The Pilot needs high Piloting skill; Engineers need Engineering; Gunners need appropriate attack bonuses; the Science Officer needs Computers. Rotating roles is possible but reduces effectiveness — match roles to character builds and practice them. The Resolve Point economy: Resolve Points are precious. Running combat without any way to recover Stamina (by not spending RP between encounters) burns HP, which is much harder to recover. Take brief rests between encounters when possible, spending 1 RP to refill Stamina. A party that never rests runs out of HP and character effectiveness rapidly. Operative and Trick Attack: The Operative's Trick Attack (make a skill check before attacking; success makes the target flat-footed and adds extra damage) is the single most complex single-character action in the game. Operatives must invest in the relevant Trick Attack skill (Bluff, Computers, Intimidate, etc.) as well as combat skills — but the damage output and utility is exceptional for a skill-based character.
Tips
- Upgrade your weapons and armor to within 1–2 item levels of your character level every tier; falling behind on equipment is falling behind in combat. - Assign starship roles before the first space encounter and build characters with those roles in mind — crew effectiveness compounds. - Resolve Points refill Stamina between encounters cheaply; never let your SP reach 0 when a 10-minute rest is available. - The Envoy's "Inspiring Boost" and "Get 'Em" abilities are among the most action-efficient abilities in the game; at least one Envoy significantly improves party performance. - Energy weapons target EAC; kinetic weapons target KAC — carry both types (or a combination weapon) for different armor profiles. - Soldier Fighting Styles define most of a Soldier's identity; choose the one that matches how you want to engage enemies and build your Feats around it. - The Mechanic's drone or exocortex is the class's primary resource; invest in it as heavily as you invest in your own combat stats. - Second Edition (2024) aligns fully with Pathfinder 2e's three-action economy — if your table is playing first edition vs. second edition changes your mechanical experience significantly.
Players and time
2–6 players (1 GM + 1–5 players) in 3–4 hours per session. Adventure Paths run 6 volumes covering levels 1–13. One-shots and Society play (Organized Play) are supported.
Starfinder Society
Paizo's organized play program for Starfinder — pre-written scenarios played at game stores or online, with persistent characters who carry rewards between sessions. An excellent way to find players and learn the system with structured adventures.
Second Edition
Starfinder Second Edition (2024) is a ground-up redesign using Pathfinder 2e's systems — including the three-action economy, four degrees of success, and the Ancestry/Class/Background creation system. It is backwards-compatible with many 1e concepts but mechanically distinct. Groups starting fresh should use Second Edition; existing campaigns can continue in First Edition.
Common beginner mistake
Neglecting starship upgrades and crew role preparation before a space encounter. Starship combat with an unprepared crew (no one specced for Piloting, no one optimized for Gunnery) is frustrating and often results in quick destruction.
