Day 18: Which RPG have you played the most in your life?

Well this is easy enough - Dungeons and Dragons! All editions combined this is easily more than half of my lifetime playing time.

Narrowing it down to a single version of the game, it has to be AD&D, the original. Because I had more time back then - so much more time! We ran multiple characters up into the teens - and even 20th once! We played through probably every published module, every Dragon adventure we could lay hands on, numerous homebrewed settings and adventures, and a bunch of random dungeons too.

It was about a ten year run for me as I didn't get an AD&D book until 1980 and it was the main game up until 2E came out in 1989. That covered all of junior high and high school and the first half of college and I spent a ton of time with it.

Admittedly, by the mid-80's we all knew its flaws but we didn't care that much - it was D&D! In between all of the others - Champions, Gamma World, Runequest, Twilight 2000, Traveller, Marvel, Star Trek, etc. it was the game someone was always ready to run, the game everyone had characters for, and the game everyone liked and knew how to play.

Honestly, that really hasn't changed. Some version of D&D has always been our core game, our baseline, and I do not expect that to change.
