Which 40k RPG should be your FIRST?

Quick summary — which Warhammer 40,000 RPG to start with, and why

Choose by playstyle:

• Want deep crunch, tactical combat, and lots of character/gear options → D100 games (start with Dark Heresy 2nd Edition).
• Want fast, story‑focused play with simpler rules and current print support → Wrath and Glory.
• Prefer a narrative‑dice toolkit or fan‑made 40k content → Genesys with the fan Dark Heresy supplement.

Big picture

The 40k RPGs generally split into two broad design philosophies:

• Simulationist (D100 games from Fantasy Flight Games)
  • Crunchy, detailed rules and deep character creation.
  • Lots of gear, talents, and subsystems; combat is tactical and often benefits from maps/miniatures.
• Narrative (Wrath and Glory)
  • Lighter, faster rules focused on storytelling.
  • Uses meta‑currencies to bend scenes; combat is quicker and suited to theatre‑of‑the‑mind play.

Gameplay highlights and differences

Simulationist / D100 games (e.g., Dark Heresy 2e and other FFG D100 titles)

• Character and systems
  • Deep customization, long talent lists, many subsystems.
  • Relatively granular character/gear differentiation.
• Combat and play feel
  • Tactical, detailed combat (ranges, fire modes, cover, lighting, stances, weapon mods).
  • Miniatures/maps are often useful; combat can feel like a tactical puzzle.
• Pros
  • Immersive and satisfying for players who enjoy building and optimizing characters.
  • Great if you like wargame‑like tactics and simulationist detail.
• Cons
  • Rules can slow play and gate improvisation via talents/subsystems.
  • Encounters may drag; requires more bookkeeping.
  • Physical books are largely out of print (PDFs generally available).

Narrative (Wrath and Glory)

• System and play feel
  • One core mechanic for most situations, with simpler rules and meta‑currencies for player agency.
  • Faster, smoother combat that’s easier to teach and run.
• Pros
  • Quick to pick up; great for story‑driven sessions and varied 40k narratives.
  • Physical books and official support/expansions are currently available.
• Cons
  • Can feel mechanically shallower over time.
  • Less distinctness between characters and gear compared to simulationist games.

Genesys (honorable mention)

• A setting‑agnostic narrative system using FFG’s narrative dice.
• There is a well‑made fan Dark Heresy supplement for Genesys, making it a good option if you prefer the narrative dice or a customizable toolkit.
• Good middle ground for groups who want narrative mechanics but also 40k flavor via fan content.

Recommendations and key tips

• Choose by playstyle:
  • If you want detailed tactical combat, lots of gear and character builds, and don’t mind crunch: go D100 (Dark Heresy 2e recommended).
  • If you want fast rules, story focus, easier teaching, and accessible physical books: choose Wrath and Glory.
• Recommended first games for newcomers:
  • Dark Heresy 2nd Edition — best D100 entry; relatively streamlined for the line.
  • Wrath and Glory — pick this if you prefer narrative play or want current, in‑print books.
• Games to avoid as a first experience (unless the GM or group is experienced):
  • Rogue Trader — large sandbox, hard to run.
  • Deathwatch — very combat‑heavy; focuses on long, tactical Space Marine fights.
  • Black Crusade — extremely dark themes and potential player‑vs‑player conflict; can be off‑putting.
• Practical considerations:
  • If owning new/physical books matters and budget is limited: Wrath and Glory is actively in production and easier to find in print.
  • If you value fan projects or narrative dice mechanics: consider Genesys + fan 40k material.
• Group and GM considerations:
  • Know your group’s tolerance for dark themes and PvP.
  • Simulationist games reward experienced GMs; narrative games tend to be easier for new GMs to run.

Final quick checklist (pick a first game)

• Want deep crunch, tactical combat, lots of toys → D100 (start with Dark Heresy 2e).
• Want fast story focus, simpler rules, current support & prints → Wrath and Glory.
• Want a narrative dice toolbox or fan‑made 40k content → Genesys (with fan Dark Heresy supplement).

Tip: If you’re unsure, ask your group what type of session they’d enjoy most (tactical, story, or a mix) — that single question usually points to the best system to start with.
