Bestselling OSR Clones

A quick run through the bestselling Old School Clones based on DriveThruRPG sales totals shown on 12th November 2012. Variants which clearly introduce their own game mechanics are marked with black titles. Systems that stick very close to the Original Game have linked titles. Prices show the full price followed by any current offer.

There are one or two other full or ‘Complete’ clones out there, but they don’t appear to sell on DriveThruRPG or I may have missed them. There are also clones of later versions of the Original Game by Dave Arneson and Gary Gygax, such as Pathfinder, which definitely don’t fall into the Old School/ OSR bracket. The B/X Companion is included, because it plays in a thoroughly Old School manner.

Dungeon Crawl Classics Role Playing Game by Goodman Games

Watermarked PDF

Features: ‘No one session is alike, the play is very random and keeps the players and referee on his/her toes.’

DriveThruRPG Feedback – ‘Randomization, heavy use of tables, critical fumbles, and no multiclassing are strong departures from what many new gamers have become accustomed to.’


Corruption by Thistle Games




Average Rating – 5

(5 reviews)

Pages 345

Features: ‘Corruption specializes in how to make a campaign more gritty, nervy and unsettling [and has] step-by-step support for adventure- and campaign-building.’

DriveThru Feedback: ‘This is my go-to Old School game. It can run a dungeon crawl for kids one day and a creepy, bloodthirsty session for mates the next.’

Watermarked PDF



Average Rating – 3.5

  1. If ever there was a blog’s post which I would love to save to PDF
    or doc, simply and easily, it would be this one. (“Simply and
    easily” means “just click a button because I’m easily confused.”)

    1. Sorry about that Chet – after all the grief I’ve had with
      hotlinking and hacking the place is locked down like Fort Knox.
      Looking at fixing some of that with more subtle solutions, but
      snowed under right now.
