I know that at least one member of our community takes formal architecture classes (Ido), and I've realized over the years I really like the way cool buildings look and that interest has been brought to the surface in TF2 because I love the way a lot of the buildings and structures are created. But I can't take formal architecture classes, as many other mappers can't, so what do the rest of you guys do for reference? Scour the corners of the internet or your city? Books? Valve maps? I really want to learn some stuff about architecture so I can apply that to mapping and also just to know since I'm interested. Can you guys recommend some books or websites etc. for me I could check out for info?
