I thought of getting the Book of Vile Darkness and keeping that around while running my game. :D Just for fun. :D
I don't think I'll ever get one of the books that tells you how best to run a character, unless it's just to get a prestige class or something out of it, because I'm fairly certain I can make power characters on my own. Only problem I have with making characters is that I can't roll for diddly. (That and I tend to play fun characters rather than characters made to get to the goal. :P)
Just thought I'd rant a bit. :) <3 D&D.
