I’m a member of various system agnostic role-playing communities. Often people ask how to deal with various GM’ing related problems, most often associated with some problematic mechanic that isn’t “realistic”.
As a consequence, a fair share of my comments can be summarised to “I play Dungeon World, where the GM decides what happens when the players roll bad. As such, this is never a problem in DW,” along with a short explanation of how the resolution mechanic work, the strong hit / weak hit / miss structure. “You could try it out?”
So, despite the fact that I’m blatantly advertising, I’ve concluded that Dungeon World is the most “realistic” fantasy RPG ever written.
