There’s this “12 RPGs for the 12th Month” thing that’s going on G+ right now, where there’s twelve writing prompts about games, one for every two days in December. This co-incidentally winds up ending on December 24th, and feels a bit 12 Days of Christmas-y without dropping the word “Christmas” in anywhere.1
The #RPGaDAY prompt for the 18th was “Which RPG have you played the most in your life?”
While I spent the majority of my teenage years playing D&D and part of my college years playing that game, my late college age group started playing Shadowrun and that’s been my go-to big game ever since. But if we use a different metric, where we look at which game I’ve played with the most number of people, that would be Primetime Adventures. I’ve run that at game days, conventions, and dropped it into my regular game from time to time.
