Well, if all you need is a h... err, I mean a stone shovel, then I'll be all to happy to remove the lumber requirements. Ahh, I see where you are coming from now. Very well, Scribes it is. Forgive my ignorance, then; the Stone Age is not my strong suit as far as historical knowledge goes. I'll fix the requirements now. In that case, would Tools AND Common Clay OR Lumber work well? Could you cite a few examples of this technique in action? I'm still having trouble picturing it or thinking of any societies that have used this technique; closest thing that comes to mind is Buddhist prayer flags, which are just plain old dyed flags, not used for recording or calligraphy. Alright then, it's in as an option. The problem with this one is that I can't have (Paper OR Wood) AND (Dye OR Lead), not that Wood would need anything but tools to carve anyway. A woodcut building could prove interesting though; maybe a little bonus for the Oriental cultures like Acupuncture (incidentally, quite a few of these older or naturalistic health buildings are still used in a therapeutic context today; I see the odd acupuncture clinic walking around the heavily Asian shopping district in my city. Might be an idea to reduce the bonuses with modern health rather than completely eliminating them). Yes, but not every town has a University either; these sorts of things are why we have the size limits system. You can only have one Department of Energy or Supreme Court, while there is no logical reason to arbitrarily limit the number of tire factories a player can build (and you'll see it would particularily deleterious under my plan due to the new unit requirements). Ah, the good old chicken and egg question! I see Chop Shops as taking in Automobiles traded from other players and converting them into Parts so that the player's war machine has some extra resources to burn, on top of adding utility to the automobile resource in more distant cities. It may be a bit moot though, since DH says he's going to revamp the crime buildings in a decidedly different manner. Nets would only really have application for those specific buildings though, while rope (which can also be used for the fishing lines proper) has a much wider range of uses. Not being an expert on trapping, I assumed lobsters could be trapped with simple lures on land, but if this is not the case, I'll be all too happy to tweak the requirements. Ah, that makes sense. I guess I tend to think of monorails as showy high tech tourist attractions rather than serious methods of transportation. Should the Monorail Station be moved back to Manufacturing then, given widespread usage of electric trains dates back to the beginning of the Modern era? I have bows and arrows as one resource for simplicity's sake; there's really little point in keeping them separate when the two resources are otherwise inseparable for all intents and purposes. It's also vague enough that I can use Archery Equipment for weirder things like ballistas or crossbows as well. My working copy of the files includes some very conservative alterations to a few of your buildings (all of which are listed in the National Wonders subheading), largely stuff like having manufacturing buildings need Factories and changing them into regular buildings rather than national wonders (though that change is in the main BuildingClass file, not your subfolder). If you want to help in this regard, go ahead; I'll shoot over the files so you can have a look over my changes and make sure I haven't FUBARed anything.
