Sometimes I wonder if the GW staff know anything about their products. All over Facebook today and in stores GW is celebrating the 25th birthday of Warhammer 40k. Except, 40K was released at Games Day in October 1987. I was there and picked my copy of RT up on the day of release.
They did the same thing last year with the 20th birthday of GW: Cambridge. Except that store opened in the summer of 1990 not 1991. Again, I was there.
