As I did for D&D, I LARPed Vampire:the mascarade (Mind’s Eye Theatre rules) before I even knew the table top game existed. I was 16-17-ish and it was… intense. A bit too much for my taste at first.
Then I went to university and started playing table top V:tM. My experience resemble that of other posters; a parity of genders, an unprecedented mixity of different people, new players that would have never join the RPG community otherwise, etc.
Vampire and the other WW games were pretty popular but did not completely eclipsed all other games in our club, but there was a marked regain of interest when Montreal by Night came out. We were not in Montreal but many of us grew up there of went out there, and witnessed the skinheads vs punks war of the early 90s firsthand, which inspired the supplement, even if violence was receding at that point. From then on, it was Sabbat games all the way…
