I don't usually keep up with this sort of legal shenanigans, but has GW sued Blizzard over, 'Space Marines,' used in StarCraft? Or is it only when it's in the title of something that they throw out C&D letters? Just seems odd as the term has been in use in Sci-fi for decades, with the earliest published form from the 1930s, I believe, with E. E. Smith's Lensman series.
