Speaking as one such excalibur GM, I know I thank you.
Folks, if you only buy one book this year, then you don't read enough. But if you buy two, one of them had better be this one.
Well written, with more info than you can sink your teeth into for dozens of campaigns, this book will keep you up 'knights' trying to think of ways to use it all in your game. (Sorry, couldn't resist the pun.)
And for the new GM, the information is invaluable, not only for Excalibur, but for any RPG. So check it out. Now.
Besides, now you have an official reason to make 'The Holy Grail' mandatory viewing for your gaming group. And make sure to offer nobility points for quotes. 'Yes, you did quote the whole scene. So here, take 10 away from your nobility.'
More fun cannot be had!
