Auto-sell option also disables interaction and cooperation between players. Players are encouraged to form colonies and work together. But on other side they are disallowed to offer cheaper products if someone go to that colony. Thats just bad design.
i totaly agree with you on that! without interaction and cooperation it's very hard to do something...
you said also to sell for euro...that's also imposible because the auto-sell option!
auto sell option its not too bat but we needs confirm this transctions. Few times i make misteake and i think not only myself. So i propose put question: You want sell prduct: xto player :y for prices :z You sure? and 2 buttons: yes or no
