I personally think you should just go ahead and try out the Mars trilogy by KSM yourself Junkyard and see for yourself if you like them. Yes there's civics, but there's science too, and both cover multiple areas in regards to the colonization of Mars.
Note that I did not say just 'terraforming', because colonization is more than that. It's about the people who make it happen as well. So what you end up with in these books, is the influence of both the technological need for the survival of humans on a hostile world, and the psychological and philosophical views of individuals or societies on how this should be accomplished (or not in some peoples views), all influencing the actions and directions taken in the overall colonization of Mars.
To me, it wasn't so much a civics or even science lesson, as much as it was a broad, possible-future history lesson of mankind exerting its individually competing wills on a new world, where in a sense humans are starting from square one.
