Yes, the iron mines limitation does it make it harder, but as we all should know, iron is a primary industry and thus primaries are shareable @ N-ice. A lot of players try not to share with others, myself included, but if there were a scenario in x2 where 2 or more players had a realistic chance of winning it, they'd have to share. Therefore if a dispute occurs, an admin should be called via sign as per usual and the problem sorted soon after..
