This game is going to fail. They have removed many loved features form Simcity 4 and scaled cities down a lot. Simcity is a legacy. Fans expect to have their game experience enriched. This game begins too look like another spin-off. They don't even have the balls to call it simcity 5. Also, it has been proven that forced online play always fails(unless its a shooter or rpg).
Here is a list of things you can forget.
God mode - No more terraforming
No "Cities" - Maps have been scaled back to about 1/4 of big sized maps in sc4
No control over your regions - You cant build in the region around your city any more.
Forced internet connection - Don't get me started
And it has been compared to this many times but I'll do it again. Its basically farmville.
