OK, I'll bite. Seems to be my week for deciding to enter contests...
Anyway, I don't
get to play, but I do DM four settings.
In the bronze-age Celtic setting Sirbalis, the characters grew up together in an isolated valley unaware of the outside world in much detail. On the eve of their coming of age ceremony, the village was attacked by ironclad armourmed figures on horseback bearing a stylized symbol resembling a bloody eye. The town drunk surprised all of them by leaping up and casting spells, throwing off his smelly robes to reveal some form of shiny armour. They were standing in the small stonehenge-like megalith when a light flashed. They awoke in an inn, two years later, in full posession of first level character skills and knowledge, on the other side of the continent. They're making their way home and trying to figure out what heppened in the last two years. There's been some really cinematic stuff happening in the first few sessions. I'm half-tempted to put up a story hour, but past experience has shown that ENWorlders are more or less apathetic at best to me high-magic, high-fantasy, high-cimena style.
The as-yet-unnamed campaign beginning this weekend is a Mutants & Masterminds game set in Freedom City, but in a para-mystical subculture known as the Underweird. The players are minor heroes who work for the Parole Office checking up on Supervillain Parolees, and getting into unusual trouble as the least important heroes in the city (as far as the public knows).
My Aelfshire and Starburst settings, each approaching their 20th anniversaries, are detailed at
