New economic victory : stock market

earning more money and you win is sucks. it's not interesting, and not joyful, even unuseful. each time everyone trying to earn dust more and more, eventually all your dust will turn into Zimbabwe dollor.

just like master of orion(2015), make galactic stock market system! someone build new galactic stock market wonder(or just trade clearing bureau), everyone unlocked stock market from marketplace,  and got a stocks as value of trading companies and systems they have.

you can make a new stock, buy stock, and sell stock. if you have bunch of stocks(maybe more than whole galaxy's 65%+5% per alliance? dunno), you will economic victory. you can defend other faction's economic victory just make more trading company/system value and making new stock.

additionally, this system can do many 'economic' things. if someone bankrupt, not sold every ships that dude have, just stocks sold automatically. if you have other faction's stocks so many, you will seizure some dust(per turn) from that faction.(or their trading company) if you have more than half of whole galaxy's stocks, you can 'modify' global ilflation, market prices, and whatever.(for 'im puppetier of market!' role play things)
