I'm not a gamer, so I just realized this when googling Meilin Miranda's latest serial and soon to be ebook The Machine God.
Games Workshops' Warhammer game also has a Machine God! Has it trademarked it?
While you might think the term "Machine God" might actually be of a valid claim for trademarking than Space Marines, once again we find machine gods in classic sci-fi literature long before the first video game http://en.wikipedia.org/wiki/The_Machine_God_Laughs
Has Games Workshop learned its lesson and will let well alone, or will Meilin Miranda's book get to enjoy the gobs of free publicity GW so kindly gifted to M.G.A. Hogarth and "Spots"?
