Once upon a time, in the Paleozoic Period of role-playing games, there was a super-hero role-playing game by the name of Villains & Vigilantes. In this game, the players were encouraged to generate super-hero, alter-egos of themselves.
Villains & Vigilantes is no more. But we have Call of Cthulhu, a completely different kind of game which thrusts ordinary people into terrifying circumstances.
Have you ever played a character in the Modern setting that was you? Would you consider doing it as an one-off game? Would it feel strange to wear your own mask for a change?
