Good thread. We need more genre specific topics to match other sites.
The most bizarre experience I had with an RPG happened outside of the game. A few years ago I was browsing one of the sites specified on the genre and saw a review of VtM:B that, in short, said that the game is pretty bad. Now, I'm not against people having their own opinion, but I can disagree with it, especially if it concerns my favorite game of all time, as I did in the comment section. The reviewer didn't like such apostasy and strolled to Twitter to make fun of me and call me names, which in turn activated my inner trolling twat and started the most idiotic bickering I've ever been a part of. I still think that the guy is an ass, but my behavior wasn't the most outstanding either. In the end, the site admin just permabanned me and everyone moved on, but that shit is out there forever, and I'm ashamed.
