Playing a lot of City of Heroes online, and I'm a Guitar Hero maniac. I'm in a Call of Cthulhu game on Tuesdays (All hail the King in Yellow!). We just finished our last attempt at conquering the World's Largest Dungeon (somehing like 8 total party kills), which means I get to run the next D&D game. I also run a Warhammer game on Sundays, using the new rules.
