They need to make money worth the same or maybe more (depending on a random inflation/dollar high) then minerals, everyone doesn't sell at the last round because there's no need to, this would fix that I reckon

Those Sound great, I think that all the rules should be changeable by the host, I think there should be options like oriinal graphics, starting minerals, chance of disasters and lucky events, handicaps (For higher ranked players against lower) short tournament games and less then and more then 4 players in tournaments, I also think you should be awarded for your name, it's so amazingly cool you could keep a side of meat in it for a week, it's so hip it cant see past it's waste etc etc
