I think if TPratchett makes AM too "real" then it will lose it's "charm" so to speak, having the city based around a certain style is all well and good but he needs to be careful not to take it too far. This steampunk thing is obviously the next step for the city, TPratchett has done well on that part but it should only be done lightly in my opinion, have working steam engines and whatnot 2 books later if anything.
1 thing I notice is that people here either want moist von lipwig in new novels or not at all and then bang on about him being in the new books (or hoping he wont be) and someone mentioned adorabelle in this new steampunk novel?.... wtf is wrong with you!?.....
