I LOVE the idea of a blacksmith's shop. It would give builders an opportunity to do something besides fix a hut. Thinking about builders again, it would be nice for builders to build the little grass huts they build now, and then as technology in the village increases, blacksmiths could fashion hammers and nails similar to how the scientists in VV2 make the spears and you could drop a master builder onto a hut to begin an UPGRADE to a hut to make it more like a modern house, with siding and everything. Doctors need a research table of their own at the hospital to firther their medical skill instead of wandering around studying plants. Perhaps drop a doctor on the hospital and he gathers several slips of the herbs and takes them to the hospital to research their use.
