dude haven't you tried it with the natural disasters mod? without it's almost no fun atleast for me..basically you will get random natural disasters damaging or destroying parts of your city.. makes you more not so carefree when it costs so much of the budget to rebuild.
I played it after initial release.
Since I am all down for green energy, I would be building wind turbines and later replace them for water-wind floating turbine thingies.
Used bank loans when down on $$$. There were few maps and I got bored, but the natural disaster mod sounds good.
TIL, traffic jams is proportional to road junctions.
And I could I also build roads with page-up & page-down to make over & under passes.
