My group usually tries to play at least a game a week, but sometimes if we're running a one-shot that goes long we'll game multiple nights in a row. We've played mostly oWoD Mage since high school, but we've gotten into some different games in the past few years, like Call of Cthulhu, Eclipse Phase and Fiasco. We've also had a few good sessions of Durance, which is another GM-less game by Jason Morningstar. As of right now, we've got my friend Alex's yearlong Eclipse Phase campaign, an oWoD Mage chronicle that the Storyteller never seems to have time to run, and the occasional one-shot with rotating GM duties.
I've been hoping to start up a campaign, as I've not GMed regularly in quite some time, but I've had a hard time nailing down ideas beyond the cursory planning stages. I was originally hoping to run Wild Talents: Progenitor, but I've always felt uncomfortable with running superhero games, as I'm not nearly as into comics as some of my friends are.
For now, I enjoy playing.
