Okay the basics, in the game design documents, are complete now.
The Conversion/Assembling/Building rules are completed.
The CSM modules concerning food & water, oxygen and energy are also completed.
I just updated the infrastructures data structure tonight, and i'll begin the heavy coding tomorrow.
Design itself is far to be completed yet, but there's enough stuff for coding now.
NB: CSM= Colony Simulation Model
Sorry for all of those barbaric acronyms :D
