The castle definitely looks like a throw-back to some of the classics that we all love (royal knights castle, king leo's castle, etc.). And this is something that i would definitely get.... i say "would" get, not "will" get.
I do enjoy the large number of wall pieces and while things are unenclosed, it is definitely a good source of very useful pieces. But... with me it's all a color issue and i have not yet devoted myself to mixing bley into my collection (except for UCS models and such). I am sure that i will pick this model up many years from now as the construction and overall look of it is impressive. But for now i'm still trying to get some older models from the mid-80s that i missed out on when i was younger.
Definitely a step in the right direction i'd say though.... at least there aren't any jellybeans here
