Why does it need to be run as admin

Hi
I can understand why a game requires admin rights to install (for example it may need to update directx etc). Ideally it shouldn't need admin privileges if it is only being installed to run under the current user account.
But why does it need to run as an admin? Will the actual release game need admin privileges to run as well? What exactly does it do with the elevated privileges required in order to run?
