Very nice to see this topic, I was planning to make a market topic myself but I seem it´s not needed anymore
I personally think that the market prizes are to high atm, and it was better in the days of the shieldpatch.
I think nice changes could be:
1:1 Sausage for timber (In older releases I remember this being a nice starting trade, but not to powerful either) (now it's 2:1)
1:1 Fish for timber (I think fish should be at least as expensive as sausages, cause of the fact a fisherman only gets 2 fishes while a butcher makes 3 sausages every time and because fish isn't for ever, so I think it's a nice trade) (now it's 2:1)
1:1 Fish for corn (same story as fish for fish for timber)
1:1 Wooden shield for tree trunk (I think it would be very nice to see, because I know without market 1 tree trunk = 2 wooden shields but if you look at the producing time for the trade I think it's not a big problem and that's what economy is also about isn't it, doubling your resources)
