[@Necroes] How well would you like for a player to know the rules?

Reasonably well. I'm requiring owning your own copy of the rulebook, either physical or pdf. If rules do get called into question, I'll be supplying and expecting page numbers. That said, the system is one designed to rely more on roleplay than mechanics, so people not being masters of the system is by far not a deal breaker.

That said, I do recommend being familiar with the setting. Unlike D&D or Pathfinder, VtM very much has a preexisting setting that the game expects you to be using.
