I enjoyed the series immensely. The economics were kind of goofy, but that shows up in a lot of fiction. Besides, it's not like humans have *never* had communitarian economics. Do you consider it impossible that Martians would set up a suboptimal economic system?
P.S.: Red Mars and Green Mars were the best. The storyline is kind of
in Blue Mars; Blue Mars seems mostly just an excuse to talk about ideas on terraforming Mars and habitable designs for other areas in the solar system. They are, however, seriously neat concepts. Red and Green have neat ideas too,
and good plots as well.
