Magic mouse + sims 3

[Freeman3030]

Hi, I'm about to buy my first ever mac and am so excited. I've been doing tonnes of research and want the basic 21.5" iMac.
I love playing the sims 3, but one thing that concerns me is the lack of a physical scroll wheel on the magic mouse.
I'm used to using all the shortcuts on the keyboard and using the mouse to navigate around my sims lots and I always use physically click and hold the scroll wheel to rotate 360 degrees around my sims lots.
As the magic mouse doesnt have a scroll wheel, is there a gesture you can use on the mouse to re-create the 360 degree spin?

I faced a similar dilemma with Black & White 2. I just remapped the rotate function to the Option key. So all you do is hold that and move the mouse to rotate the camera. It's a little different at first, but you get used to it.
