8) Banking / Winning
You can now put strat gold into a banking account. There, it will receive interest of 2% per day. You cannot take money out of the bank account. At the end of this round, there will be (about) 200 looms given out in total. To distribute it, all of the money in the bank will be summed up (eg 1,000,000), then divided by the amount of looms (eg 200). This results in the threshold to be guaranteed a loom (eg 5000). For every 5000 in your bank account, you would get 1 loom. If you don't have exactly 5000, the rest money will be used for a drawing (if you have 6000, you have 1 fixed loom + a 1000/5000, so a 20% chance, to win a loom. Works also for people with less than 5000 in total)
9) Towncenter
Whenever you are in a fief, you can put goods into a towncenter for other people to buy. You do this by increasing the selling price over the fief limit. You have a separate tab to view all offers around the world at all times, so you can plan trading routes.
10) looting system has been changed. no more randomness. at the end of a battle, the winner receives all of the goods of the loser. the items that were used receive a penalty of -2 to it's loom level and are distributed 25% to the loser, 50% to the winner.
11) retreating is actually surrendering, all rules of #10 come into effect
