My idea is this. Space has been privatized and billion dollar corporations are in a race to colonize mars. But not only must they compete with each other but they must also compete with a previously unknown alien race living in mars.
3 players play as the human companies
1 player plays as the alien race.
The humans win by being able to produce so much (ala Axis and Allies)
The aliens win by killing so many humans.
The aliens produce more units by converting hexagons into "Hives". They get one grunt for each hive and in turn can combine grunts to make better units.
I have alot of good ideas for units for the human race but not a clue on how the humans will buy them.
The board will be modular like Settlers of catan, but o fcourse bigger and look like mars.
The only thing I really need is an idea on how the human economic system will work. I dont want anything like axis and allies where each hex is worth X amount. And I want something that the alien race can affect some how.
The way I imagined my game scaling is by the Hex map than can be as little or as big as people want it to be. Also I want the humans to be able to trade but not HAVE to. After all they are competing against each other also.
