RPG Types by Genre and Lore Scope
Beyond rules density, RPGs differ in genre (fantasy, sci-fi, etc.) and lore scope (open vs constrained). Here’s how they break down:
1. Generic Systems
Definition: Flexible “toolkits” designed to run in any setting.
Examples: GURPS, Savage Worlds, FATE Core, Basic Role-Playing.
Strengths: Perfect for DIY worlds or mixing genres.
Weaknesses: You must supply most of the lore and tone yourself.
2. Fantasy RPGs
Definition: Games built around magic, monsters, and mythic worlds.
Examples: Dungeons & Dragons, RuneQuest, Tunnels & Trolls d6 only.
Strengths: Most accessible; classic dungeon crawls, quests, and epic stories.
Weaknesses: Can feel samey without unique setting twists.
3. Science-Fiction RPGs
Definition: Focused on tech, space travel, cyberpunk futures, or alien worlds.
Examples: Traveller, Stars Without Number, Shadowrun (sci-fi + fantasy hybrid).
Strengths: Great for exploring politics, tech, and “what if?” questions.
Weaknesses: Tech detail can overwhelm new players; tone varies widely.
4. Themed / Lore-Constrained RPGs
Definition: Bound tightly to a specific IP, world, or mythology.
Examples: The One Ring (Middle-earth), Star Wars RPG, Warhammer Fantasy Roleplay, Legend of the Five Rings.
Strengths: Rich, detailed settings with instant immersion.
Weaknesses: Choices may feel limited by canon boundaries.
5. Open vs Constrained Lore
- Open-Lore Games: Worlds left broad or vague, inviting GM/player creativity (FATE Accelerated, Savage Worlds).
- Constrained-Lore Games: Heavily defined worlds where canon directs play (Middle-earth, Star Wars, Warhammer).
Tip: Decide whether your group prefers limitless creative freedom, or immersion in a beloved setting with strong expectations.
