"Upgrade Suggested: Unfortunately, your OS does not meet this requirement."
Lolwut?
This happens if you have Windows 7 or something and you run an older game check.
AoM works on Windows 7 as far as I know, I've played it before on my computer.
Also if it says you meet recommended/minimum and you still lag like a bitch its likely because you either have a butt load of programs in the background drawing usage or any other thing like excessive dust, underclocked rates, etc.
