I mostly run scifi and superhero games, from Gamma World to space opera, using the Alternity game mechanics. I've recently started running games set in the Firefly setting as well. I had a gamer group that signed up for my games every year but many of them aren't attending this year so I'm sure I'll have many openings. Below are submission descriptions of the games I'm running this year. Maybe you can give one of them a try.
Return of the Kestrel
Star Force Captain Hylund and notorious smuggler Brade Moro find themselves marked for extermination as they race to uncover an alien conspiracy. Set in the StarDrive universe.
The Corrupted are being recruited by Demons and only the psionic knights of the Seraphim Order can hope to defeat this infernal threat to the Five Heavens. As the mighty Seraphim, you will wield psi swords and mind powers at the command of the Crowns of Heaven, the sovereign lords of the five planet ships that orbit the war-scorched wasteland that is Earth.
Batman Adventures: The Joker’s Wake
After the Joker is caught in a deadly explosion, Harley Quinn is determined to give her puddin a murderous sendoff that Gotham will never forget.
Firefly Adventures: Prison Break
Jayne’s brother has been snatched by the law. Do I really need to go on? Gear up and get ready to misbehave.
I will also be running a 4E Dungeons and Dragons game. Not sure if that's your cup of tea though.
An infernal gem of ancient power has been retrieved by valiant heroes and now it draws them to the Moonspear Sea where the Hellcrown waits to be restored.
