well, got a bit disappointing knowing it's like a modified version of other SimCities. I already have the game btw...
In any way, very nice...although I haven't yet felt the difference, I don't think the society plays differently from CiberPunk (the one I'm using the most) to Authoritarian (tried to put a "People's Square" and came out an hardcore fascist square with mostly no purpose. There's nice things to control, like traffic, I saw the firetrucks taking so much time to put the fire out and even more to go back to the fire station that I spammed public transports like Underground or Bus Station and now my streets and clean again.
Speaking about clean, you can build 100% clean city. Buildings using their own solar energy, solar power, wind turbines and whatever else. Bad thing is, they don't exploit all the possibilities of clean energy, they even have hydrogen plant, natural gas, and whatever else.
So...what this modified version doesn't let you do as much as the other games?
Well, you can't mess with economy, only with society and business economy, it's an harsh race to make them spend allot.
