I guess the point is, in the end, "try playing WoD once instead of D&D".
I wonder how many D&D players would go over to Vampire if every group in the country had to play one single game of it.
I know that when I tell a D&D-shocked player that "basically, it's the real world with police and cell phones and people who care, so people will react if you do crazy shit", most of the time they go crazy with it and have a great time with the consequences.
Some of them have so much fun they even roleplay, and some even well.
The thing is, it's suited for the stuff a lot of problem D&D players seek (a power fantasy, k3wl p0w3rz and action-movie scenes) better than D&D itself, and the game comes complete with a shitton of advice and material that let even me and my group grow up and have fun back then.
It has everything you need for a stupid-ass katanas and trenchcoats game, everything you need to keep a horde of neckbeards satisfied, with werewolves, zombies, ghosts, eldritch spirits, God, Satan, demons, vampires, fae, flamethrowers, Celerity, Necromancy, hunters, conspiracies, sex, violence, blasphemy, what have you.
And then, when everyone has gotten their juices out and played like six Sabbat games, the group naturally kind of matures, because the corebooks are full of advice and ideas, and the game world is by definition richer by virtue of it being "our world, but so bad that unthinkable things can happen, with mountains of fluff and metaplot on top".
Even players who get in by burbling about Baali can mature, because the fucking corebook is a crash course in roleplaying that leaves new players able to go so much fucking further and have so much more fun.
I've seen that myself a lot of times considering I've played for a changing roster of neckbeards and special kids at a youth club.
I'm running out of space, but to my experience Vampire has never bred as persistently and stubbornly shitty players as D&D. The worst part is they rarely even have much fun.
