Age of Empire III on 13" MBA 2012 w/ ML

[mbanewuser]

Hello, I recently switched to Mac and I used to play Age of Empires on my Windows computer. However, I can't play the version I have without bootcamp or a vm. I was thinking about buying the Mac version III since I used to play vII & vI on Windows. My questions are :
- Does AoE III run on ML ?
- Does AoE III run on integrated graphics, so in my case Intel HD4000 ?
- Has anyone tried playing using a dmg image created using Disk Utility (from the official disk), so that it would allow me to play without DVD player once installed ?

Thanks.

NB : I have an USB DVD player.
EDIT : I forgot to say that I have : MBA 2012/128GB/8GB/i5
