There's plenty of information on the Westwind game in this forum. Just look around a bit and you'll certainly find it. Malamute used to play the rules and liked them. You'll need a lot of houserules and possibly a gamemaster who is familiar with the rules.
I'm about to post houserules for Chaos in Carpathia that are written with the Transylvanian part of the Westwind figure range in mind. This will include 9 warband lists (various humans, romanian vamps, nosferatu, werewolves, frankenstein, gypsies, the brotherhood), 8 scenarios (some original ones, some completely new) with a new victory points system and a campaign system (not using character advances though). I'll have everything complete by christmas.
Carpathia is better suited to one of games without much preparation whilst Vampire Wars needs somebody to work out a scenario and run the game. Both rulesets accompany each other very well.
