I admit that i have never liked the gyrocopter, or the humorous tone taken to both Dwarfs (pointedly without the V) and Orcs, but it is important to realize that the warhammer world is much more advanced beyond the standard D&D game. Bretonnia is the place to go to avoid handguns. The Empire is 16th century Germany, not 13th century France. Steam tanks, repeater rifles and handguns (both of which are infeasable to physics), and the dreaded Volley Gun are all extremely rare and fit well into the sub plot of humanity's friendship with Dwarfs, and the Hochland longrifle is essentially an super tooled up musket, expensive and rare and completely fitting within the time period, when fortunes were spent on hand-crafted guns from dueling pistols to hunting rifle, if for no other reason than to get them to shoot in the forward direction and not explode. And Skaven without warp technology would simply lose all flavor and become wererat look alikes. Essentially, in a world with elves, dwarfs, dragons, daemons, and magic, having technology go a little over the top isn't really going to mess things up too much. It's like the critic who complained the tomatoes were mentioned in The Fellowship of the Ring, saying that tomatoes weren't indiginous to Europe and somehow failing to note that Hobbits weren't exactly wandering around Capetian France either.
I, personally, am looking forward to the mutants. I hope someone will finally come up with a good system for chaotic mutations. And I dearly hope that this version of the rules will not be as restrictive, complicated, and byzantine as the last set. It would also be nice if it dealt with developements that have happened to the story line in, oh, say, the past ten years, which the "re-release" that I bought did not.
