From what I remember, no one ever wanted to play Werewolf, but lots of people wanted to play A werewolf in whatever Vampire game was going on. Even though they were supposed to be (im)mortal enemies.
I liked Vampire okay, but it always bothered me that all the other WoD games seemed like variations on this obvious formula of factions and infightings. I thought having different tribes/bloodlines of Werewolves was kinda lame. I always thought it would've been more interesting if they had based it more on the curse/full moon/unwilling transformation part of the myth.
I did like the power level of it. Something about it really captured the feel of intense, superhuman violence. Maybe it was because after playing vampires, who can so totally destroy normal humans, playing a werewolf ripping through vampires seemed unbelievable.
