I think the share marker should be real time.  It will help make it more active.

But keep the 5% limit per game day or for even 7 game days..

Also… When a new company is formed would it be possible to have a 30 game day delay before those other shares go to the market?

Also…haha… To get very realistic.. Require a player/company to choose an underwriter when they are going to own less than 100%.  This way if the CEO has a proven track record of making massive profits the underwriter will hold off on selling those shares to make a greater profit.

My plan is to play as an investor only.  So tools like this would really help.
