But I like the idea of politican-as-vampire, and I think that White Wolf missed a trick in going down the teenagers-and-ennui route. (Financially they didn't miss a trick, but in noisms' Ranking of Good Games they certainly did, and we all know which of those is the more important.) I really think there's great potential for a game about vampires in the Corridors of Power, whether in Westminster, Capitol Hill, the Diet, or whatever country you prefer. I say this mainly because vampires and politicians are practically indistinguishable from one another, but also because I just saw the film Il Divo, the story of Giulio Andreotti, three-time Italian Prime Minister, who happened to bear a striking resemblance to Count Orlok of Nosferatu fame - both in looks and personality. This then reminded me of Michael Howard, one time Home Secretary in one of Margeret Thatcher's cabinets, who famously resembles a vampire, not least in having Romanian ancestry. (Anne Widdecombe once offhandedly remarked that "there is something of the night about him" - one of the most notorious comments a British politician has ever made about another.)

I think some political systems would be more amenable to this sort of game. The Japanese Diet, and the Italian Parliament, with their well known ties to organised crime, would be the easiest to envisage being populated by vampires. The more open British and American systems, with their intense media scrutiny, perhaps not so much. (Although trying to maintain a blood habit while avoiding the prying noses of journalists could be a great game in and of itself.) Play could revolve around all kinds of corruption and derring-do - from assassination of rivals to bribery to tabloid indiscretion. I think I'd be more inclined to use a diceless system to run it, though - maybe Amber (if I ever get around to properly reading it) or Nobilis.
Or perhaps Risus...
