If you have played any other sim city game, there is nothing new. it was more difficult to play with the wii controller as well. I found the controller quite inhibiting and did not like playing the game at all.
The game itself would be a good game if not for the erratic movement of the cursor. The slightest motion sends it flying across the screen. It can become very maddening. The graphics are good and so forth, it just is not a good game for anyone with a short attention span and/or very little patience for ridiculous things like that (like me).
