I liked this game, but it would NOT stop asking me for things. Save info on my computer, get coins, I am done. Whoever made this game, your incessant begging earned you a low rating.
The makers of this game were pretty ham fisted with the environmental message. You are supposed to research all the clean technologies and switch to ethanol or electric power and leave those nasty coal and nuclear wastes behind. Then the game becomes too easy. Yeah, well you know what developers? Screw. You. I just finished playing with coal power pumping out smog and an army of garbage trucks turning the air purple. My engineers carry nuclear waste nonstop due to all the plants I have. Now the game tries to punish me yes, but with a little strategy it was too easy to get around that. I. Win.
