If you played against the AI and want to ramp up difficulty or want to play against other players. These misssions teach you all the tricks you need. If you want to test if you mastered the tricks then try the challanges.
At first glance this might seem like a simple game. Gather resources build your base sell the expensive resources to build a space rocket for casah to buyout the other players. Then you realize you can get ahead by predicting whih resources will get cheaper so you dont have to produce them. Which resource will get expensive if you control all the basic sources now and only sell the products depending on it. What if you play with robots and dont have to worry about food or water? What if you can steal other peoples rockets fora little while and then buy them out before they can cash in on it? There is usually atleast one trick which will get you ahead of the competition on every mission against AI even on CEO level.(I am not a Guro) Add in that the GOG version has the best DLC and you only want to buy Blue Ship if you really want to learn how to play if you increase the difficulty above the AI or The Patron and The Patriot if you cant get enough of the campaign mode.
