Gnometown Hero
I have been watching his (extremely expressive) videos! I don't have the space (or interest) for solo miniatures gaming, but the other stuff has been extremely educational, including the advice of not going overboard with random generator books. I'm keeping myself to one per game. (For Colostle, it's the Roll & Play Fantasy Gamemasters Kit, although I haven't needed to use it yet.)
