A little late posting to this topic but...
DO NOT BUY THIS GAME... if you enjoyed any of the previous simcity titles.
It is unfortunately completely different, and not in a good way. For a start you can't zoom all the way out! how am I meant to see my city in all it's glory and natural disaster it back to the stone age?
It has an odd 'place building type x' interface (think C&C where if you wanted a barracks you would place a barracks - but with 50 types of barracks).
I loved the 'zone' function of the predecessors and just waiting to see what popped up in an area was one of the best ways to fill the 'dull' moments.
It has a 'meet x criteria to build y building' - this takes away all of the joy of micromanagement and just sees you building 20 'trailer parks' in the beginning of the game - very un-aesthetical.
The graphics are... um.. shoddy... just plan lacklustre...
So if you've never played a simcity game.. go for it, you might just love it.
If you've ever enjoyed a simcity game -
stay away!
