Since I joined the group, we’ve been playing either Delta Green (check for kinnygraham’s Actual Play on rpg.net) or Gaslight Cthulhu. Michael’s RuneQuest represents the first game where we haven’t had guns and we are not playing characters who are completely in the dark.
We’re playing inhabitants of a world where Magic and the Gods are real. We accept the truths we see. Visions and dreams have meaning and while the appearance of a half-man-half-goat brandishing a sword might shock the delicate sensibilities of a Victorian gentleman or a Air Force Deserter, to a Templar of the Sun Dome it’s just something that needs killed and burned.
It’s a very different experience. We must play as if we are confident in the world, we do not express surprise at the Morokanth and we should be well-informed about the behaviours of the rare but dangerous dinosaurs that roam the plains.
They use the same system but the method of play is exceedingly different.
