I'm gearing up to run an episodic, competitive game with my group. Each episode, two factions compete for a prize, and only one can win. Players have both a public declared loyalty and a secret true loyalty—and personal goals which might conflict with their faction's goals, and the liberty to switch sides. I'm, uh, hoping it'll work, rather than dissolve into... something that doesn't work.
So what makes a competitive game tick? I'm only really familiar with Shinobigami and In a Wicked Age on the RPG front... and only barely, read-through-it, familiar; not "played extensively" or even "played once" familiar. And related, but not quite in story game land, are things like Battlestar Galactica and Resistance.
Who's got experience with this sort of thing?
