Think about this.
Every certain period of time modules comes to the colony from earth. Moduels and a few people more. the better you manage the colony the more people will arrive.
Have a space station to accept and send this trafic to Mother Earth.
From place to place (tile to tile) you can only send engineers with space suit for walks.
When the structures are done the sites are connected with a tube (mroe trafic)
They all look like domes...
Ideas that come from ceasarIII and Dune the building of a dynasty.
Also it limits the need of graphics. Few sprites to do the mars walk and maybe a MarsBagy... and then just animated tubes realy!
What you want to do it make a draw of what you want to see and post it on your walls. This is good focus aid.
Then think in arrays. make a hyerarchy of structures building and draw dependencies. and on the lines put a when.
so have:
Platform (no dependency)
Worksite (dep on Platform)
Powersite (dep on platform and Worksite)
Living Quarters (dep on PwrSite and Platform)
And then make attributes
Prosperity (dep on worksite) applies on Living Quarters
Population (dep on Prosperity)
Resources (reduced on Prosperity / population)
All that will make your head spin and give a headache... Look at the posters on your room and take an aspirin!!!!
GOOD LUCK
