Re: Dark Champions Campaigns
I've run Dark Champions, and a Cthulhoid Champions game. But even my 4-color games tend to get dark -- I think it's the nature of the players I have. One beautiful young woman (a new character) was rescued by the group from an experiment conducted by the villain, and the first words out of her mouth were, "I'm going to kill him. Anybody have a problem with that?"
I often have world-spanning conspiracies, light and dark, and the US Gov't is tied up in most of them, light and dark. Some times there's nothing scarier than an IRS auditor.
As for the 'weird' influences, I've had Nyarlehotep show up as a government 'black-ops' specialist, Yog-sothoth as a televangelist, and Cthulhu as a humanoid (but green) woman. As pets go, you can do worse than a Hound of TIndalos, depending on who you need kept out of your base.
