Not as bad as the Gamespot reviewer says...
I admit the game is easy - hopefully this might be tweaked by a patch. It does get more difficult as your city grows and you have to balance out several factors. Some more in depth SimCity style decisions and play could be added on by an expansion I guess. However, I don't think this is the whole point to the game. After you've been playing for a while you get strangely addicted and just want to keep on adding a little bit more to your city.
The engine does need some fixing but I haven't had too many problems since I applied the first patch.
I'm really enjoying building a city how I'd like it to be built. You can build anything form small agricultural town up to an Orwellian nightmare straight out of 1984 – let your imagination go wild!
