maybe i ask you iff you will make the plot a litte bigger.
let me tell how the game and simulation can be for gamers a knewl and a nice experience
1st They start a ship to Mars (3-4 options a, b single ship, a supply ship and a crew of a second ship c, send more ships with equipment and two crews to Mars
(I mean the player explores the art of travel in - has the possibility to share the charge-exchange (more water, more technology, or even more crew))
2nd Can happen on the flight to mars 2-3 accidents (from 40 options to pass 2-3 / suicide, loss of food, water contamination, broken radio, etc.) which makes it difficult to start the base of the Mars
3rd Landing on Mars (not simulated only one card vomplaneten and 20 possible landing points)
then it would go on as before (Fit base, ore looking water, etc.)
i know a lot of thinks to do, only a info how the stuff will get more fun
