Perhaps, but it true nevertheless.
There is no requirement on Creative Assembly to produce a game based on real world history. They could just go to town with something like Command and Conquer Red Alert. Instead they chose deliberately to target a market with people like me in it, who have an interest in military history and thus will buy their game simply because its based on actual historical facts.
Having targetted a market that is looking for authenticity, it seems only reasonable to expect that designers bother to do some research and actually produce what they promise. Had ETW featured Orc's and Goblins I might still have bought it, but would really be annoyed if the goblins couldn't fire from the back of their wolves, but the fact is horse archers could and did fire whilst moving. I actually have video footage should how it was done and exactly how accurate it was.
Incidently, just for the record I consider the same rules apply to film makers, and TV producers. Basically, if you can't be bothered to get it right then just don't bother in the first place, would be my message
