A Mechanical Tour of Dungeons & Dragons Editions

From Expert Sets to the 2024 Rules Refresh

Dungeons & Dragons has evolved by changing priorities, not by replacing ideas.

D&D Timeline from roleplay-geek.blogspot.com

Each edition is a response to how tables played—and what they needed next. Also note that releases were not specifically in edition order in the beginning of times. I'm talking to you D&D BECMI!

This article walks edition by edition, clearly labeled, focusing on:

• Mechanical intent

• Player quality-of-life (QoL)

• Dungeon Master quality-of-life (QoL)

Closing Perspective: Editions as Design Answers

Each edition answers a different question:

• B/X–BECMI: How do we make exploration scalable and clean?

• AD&D: How much authority should the DM wield?

• 3e: What if everything was explicit and customizable?

• 4e: What if balance and tactics came first?

• 5e–2024: What if flow and accessibility mattered most?

No edition replaces another—they prioritize different experiences.
