Don't know if this group is active or not, but if you don't mind answering my questions It would be much appreciated:

So I recently found and bought this book: Vampire: The Masquerade

But I have yet to fully understand what it is. So I know that its a game, but I don't quite understand what type of game. Is it a PC game? Board game? Our is it just roleplaying? Also what are the books for? The only thing I could think of after reading a little bit of it and looking around it, it seems like a very big guide book to a game. I also ran into a second addition character guide but couldn't buy, it was is that for? Is their some order that the books go in?

Again I would appreciate if anyone would answer my questions.
