I played all day yesterday, without any problems. I live in Utah, and even playing on the East US (it wouldn't let me choose any other server) server, I was fine. Today, I can't play. If I can make it in the game, it says I'm not connected and I can't do anything.
@df: Difficulty wise. Control wise applies as well, though. In Sim City 4, it was possible to fail. I failed a lot. In my first go at this new title, I didn't take things to seriously, I just expected to fail right off the bat. I have a very successful city!
I've been playing for a while, and you should officially wait on this one. It's got a lot of issues. Fortunately, it also has a lot of potential. The game needed another year in development. They could have fixed the strange road and auto-terraforming, and expanded city size. It's also a really easy game.
