Ars Technica seems a little underwhelmed : http://arstechnica.com/gaming/2013/03/simcity-impressions-we-waited-ten-years-for-this/
It's interesting they say it's unforgiving when all the Sim City 4 die hard were complaining it seemed too easy.
Also comments on how they don't see how they can get to the great wonders and then later say they feel it's a small game. They do just seem upset it's not set up exactly like Sim City 4 and they need to approach it in a different way.
