Just finished some playtesting of Humans. Their trade-based system works fine and is well made. The wholes license and coins side of things seems well balanced. It seems to me that the most effective way to make money[Bar renting out a ton of merchant stalls] is to buy stone at the stone stall and sell stone crafts at the craft stall. Except the craft stall didn't have any reactions. Neither did the Tavern. I'm assuming that the Tavern's lack of reactions was just because the Humans are unfinished, although all the other local trading stalls had reactions, so the craft stall's lack of them might have been a mistake. The Human cave-adaptation is a PAIN to deal with. Just building normally is WAY too difficult. 8 to 1 block ratio would help, but you would have to GET stone in the first place. The Carpenters Guild Sawmill requires you to have gold, which you can only really get via renting out stalls, which you can’t do until at least second Spring. I only manage aboveground stuff with Kobolds because they have leather and bone blocks aplenty by mid-game and have a decently accessible sawmill. Plus, they don’t tantrum, so getting dining rooms and dormitories isn’t a priority. Eventually, I ended up channeling out rooms from aboveground, removing the ramps, roofing it over and then putting in whatever I wanted in that room. Because there was no way I was making enough blocks to make actual buildings[I found out about the 100 granite block test reaction in the still later. Even then, I would have had to run it 2-3 times to actually build even a basic wall around some workshops with a dining hall and a dormitory, let alone roof it off to protect from fliers.]. So Humans DEFINITELY need a way to make absurd amounts of blocks. The 25 marble or obsidian blocks reactions in the Humans trade stall seemed like they were on the right track, but were super overpriced[100 gold pieces PER INDIVIDUAL BLOCK? THE HELL IS WITH THAT?] Maybe add in a buy 25 granite[Or another more common stone] blocks to the Human stall for half the price of the current buy 25 marble/obsidian block reactions?[Or even less. But that might tip the balance too far the OTHER way.] Also, adding in a "clear workshop" reaction to the local stalls would help immensely. I spent a lot of time constructing and deconstructing the local trading stalls to look at their reactions. The sell leather for 150 copper actually gives you 500 copper, for the record. Not sure if you can actually make a reaction give less then that. If that’s the case, I recommend buffing the yield on selling rarer types of leather. Also, THANK YOU for letting us sell bags of feathers at that stall. They usually just sit around and annoy me with their clutter after I murder a bunch of flightless birds. And I ended up with a steelclad horse as one of my pack animals. I butchered it and melted down its steel armour thing for 10 whole steel bars. Since steel is supposed to be mid-late game tech for Humans, this seems like an exploit.
