It’s a sad day for gamers everywhere, as Dave Arneson, the co-creator of D&D and the first DM ever, has passed away from cancer. He was lesser known to a lot of gamers simply for no other reason than Gary stuck around longer at TSR. This is no less reason for him to be mourned, however. He was the first DM with his Blackmoor campaign setting (the first ever, even before Greyhawk), and paved the way for a few of the most fun parts of this hobby: creating worlds and great story telling. He will be missed.
There were originally some conflicting reports on whether he had truly died or not, so I was waiting for some decent confirmation before I said anything.
PS: This latest Order of the Stick comic is a brilliant homage.
