I'm Jeff Okamoto, the GM and site admin for the Gaming Grunts. I got back into gaming after listening to YSDC and RPGMP3 and started recording sessions which are published on our site. We've been up for just over 5 years now.
My favorite gaming world is Glorantha, mostly because I got to play in Sandy Petersen's group when he was working for Chaosium. I've played in Glorantha using RuneQuest II, RuneQuest 3, and recently GM'ed using HeroQuest 2. Although the Gaming Grunts started out playing Call of Cthulhu, as you can tell from our site, we've branched out into a number of different systems. We'll shortly be releasing a Deadlands Reloaded campaign.
