CalCon is a local games convention which ran last weekend. A brief story (one among many) that comes to mind:
We were getting near the end of an RPGA D&D 4e adventure, and we’d been playing for about three hours solid, and the DM set up the last battlemat and described the scene. He was using generic monster counters, numbered, instead of miniatures.
After three rounds of combat, I finally noticed — hey, you never told us what we’re actually fighting! Laughter and chagrin all around. Oh, it’s goblins, like we were fighting before. Okay.
