In one paragraph:SWURPG runs on the same d20 engine D&D 5e players already know — same action economy, advantage/disadvantage, proficiency bonus, and HP/AC math. The difference is what you build with that engine: blasters and lightsabers instead of swords and spells, the Force instead of arcane magic, 90+ Star Wars species instead of fantasy races, era-agnostic play from Old Republic through First Order. If your table can run 5e, it can run SWURPG with ~15 minutes of onboarding.

What stays the same
If you've run 5e, the SWURPG learning curve is mostly cosmetic. These core mechanics are functionally identical:
- Ability scores. STR / DEX / CON / INT / WIS / CHA, modifiers computed the same way, point-buy or rolled the same way.
- Action economy. 1 Action / 1 Bonus Action / 1 Reaction / Move. Movement, dashes, disengages, helps — all where you expect them.
- Advantage / disadvantage. Identical rule, same trigger pattern (cover, attacks on prone targets, hidden attackers, etc.).
- Proficiency bonus. Same +2 → +6 ladder from L1 to L20, applied the same way to attacks, saves, and skill checks.
- Skills + ability checks. d20 + ability modifier + proficiency vs. DC. SWURPG has 19 skills tuned for Star Wars (Use the Force, Mechanics, Pilot, Tech, etc.).
Where SWURPG adds Star Wars depth
The Force is not Vancian magic
5e's spell slots are baked into Vancian preparation (memorize spells, expend slots, recover on a long rest). The Force is a single FP pool — closer to sorcery points than to spell slots — that you spend freely on any Force power you know. Some powers are cheap (1 FP, used every fight); some are expensive (6 FP, used once a session). Force users feel different from D&D casters.
Damage types are mechanically distinct
5e's damage types are largely flavor (most monsters resist a few; most attacks deal one). SWURPG's damage types matter strategically — droids resist kinetic but take double from ion, energy shields stop blaster bolts but not vibroblades, sonic affects organics differently from droids. Picking the right weapon for the encounter is a recurring tactical decision.
Range tiers, not range numbers
Where 5e tracks weapon range in discrete feet (60/180), SWURPG groups range into tiers (Short / Medium / Long / Extreme) with disadvantage at higher tiers. Same math, less measuring. Faster theatre-of-the-mind play.
Droids as a playable species
Droids don't breathe poison gas, don't eat, don't need sleep, and can't be healed by medpacs — they're repaired instead. They're a full first-class playable species with their own ability spread, plating system, and chassis upgrades.
Starship combat as a layered module
SWURPG ships with rules for ship-to-ship combat with pilot, gunner, and engineer roles, system damage tracking, and a separate ship-scale action economy. 5e handles vehicles at a high abstraction (or punts to 3rd-party); SWURPG treats them as first-class.
Which one is right for your table?
Stay with D&D 5e if…
- Your group is in the middle of a 5e campaign you love.
- You want the largest possible TTRPG player base.
- You prefer fantasy tone (dragons, dungeons, magic).
- You already own the books and use D&D Beyond.
Try SWURPG if…
- You want Star Wars adventures with the 5e mechanics you already know.
- You want a free character builder and free rules access.
- You want starship combat as a built-in system, not a bolt-on.
- You want to play droids or other non-humanoid species seriously.
- You want a system in active development with regular updates.
Frequently asked questions
- Is SWURPG basically Star Wars 5e?
- Mechanically, it's close. SWURPG borrows 5e's action economy (1 Action / 1 Bonus Action / 1 Reaction), advantage/disadvantage, proficiency bonus math, and HP/AC framework. So if you've played 5e, you're already 80% of the way there. The remaining 20% — the Force, blasters with energy/kinetic/ion damage types, droids as a playable species, lightsaber forms, and a 90+ species roster — is where SWURPG diverges to be Star Wars rather than fantasy.
- Can I convert a D&D 5e character to SWURPG?
- Not directly — the species, classes, and equipment are different — but the math feels nearly identical. A Lv 5 Fighter in 5e has roughly the same combat output curve as a Lv 5 Soldier in SWURPG. Proficiency bonus scales the same. Ability scores work the same. The fastest path is to rebuild the character from scratch in the SWURPG Character Builder; it takes about 5 minutes once you know what species and class you want.
- How is the Force different from D&D 5e spellcasting?
- 5e uses spell slots — fixed per-level resources spent on individual spells. SWURPG uses Force Points (FP) — a single pool that refreshes on a Long Rest, with each power costing a specific FP amount per activation. Force users can spam cheap powers (1-2 FP) or save up for big ones (4-6 FP). There's no spell preparation step; if you know a power, you can use it at any time.
- What does SWURPG have that D&D 5e doesn't?
- Beyond the obvious (Star Wars setting), SWURPG ships with rules for: ranged combat at varying distance bands, energy vs. kinetic vs. ion damage types, droid characters (with repair instead of healing), starship combat as a separate action-economy module, lightsaber forms (Soresu, Vaapad, Juyo, etc.), and an era-agnostic design where every rule works in the Old Republic through the First Order.
- Is SWURPG more or less crunchy than 5e?
- Roughly the same baseline complexity, with depth in different places. SWURPG has fewer total spells/powers (~60 Force powers vs. 5e's 300+ spells), fewer classes (6 base + 18 advanced vs. 5e's 13 base + many subclasses), but more granular equipment (damage types, weapon properties like stun/sonic/ion, modular upgrades). If you found 5e magic preparation tedious, SWURPG's Force system will feel lighter. If you loved 5e's spell variety, SWURPG will feel narrower in that one area.
- Can I use my D&D 5e dice and books with SWURPG?
- Yes — SWURPG uses the standard 5-die set (d4, d6, d8, d10, d12, d20). You don't need any books; every rule is on swurpg.com for free. The 5e Player's Handbook isn't required and won't translate directly, but the underlying d20 math is shared. If your group already plays 5e, you can teach SWURPG to them in about 15 minutes of differences-from-5e onboarding.
- Is SWURPG free like the D&D System Reference Document?
- More open, actually. The D&D SRD covers a subset of 5e for third-party publishers but excludes Player's Handbook material like most spells and subclasses. SWURPG is 100% free in full — every rule, species, class, Force power, item, monster, and adventure module is on the site at no cost, with no paywall, ads, or login required. The character builder and PDFs are free too.
Try SWURPG
If you already play 5e, the Character Builder will feel like a Star Wars reskin of your familiar workflow — pick species, class, abilities, and gear, then export to PDF. Onboarding time for a 5e-fluent player is ~15 minutes total.
