The campaign mode is still very confusing. 

The goal would appear to be about creating stable revenue streams which you can use to buy colony improvements.

Colony improvements which do not have a dynamic cost - there are no resource requirements just a flat sum of money, correct? 

Do colony improvements resource drains affect all players equally? Or does it only affect the purchasing player? 

Does colony improvement placement location matter? I imagine that much later in the campaign with off world markets it will matter where warehouses go. But right now it seems like the colony automatically places the next set of improvements. Is there a way to bring up a display for where the next improvement for each type will go down?

Will you have to purchase HQ Upgrades from the "improvement" buy of the game phase? 

Do you have to play each location found on the start of the campaign or do you only play in one location? How many locations will you play in total? Does each location last for the "# of days" selected during the start of the campaign or is that how many locations will be played? 

Does Campaign mode emphasis teachable moments that would improve a player's multiplayer game or is it too radically different?
