Hi! i played empire earth as a kind and just found it here!
But there is a issue, it says that it is not compatible with most intel Video cards.
Am i able to use my current video card or do i need a new one?
by the way the exact type is a "Intel Iris 1536 MB graphics" on a mac
Thanks

GOG doesn't offer or support a Mac version of the game yet and explicitly states that the game is incompatible with most Intel graphics chipsets, so I'd be careful buying it. You could only try running it in a simulated Windows environment but GOG support won't help you on this.

Do you know it it is possible to hook up a external Video card?
I can get windows pretty easy so thats not a problem.
Thanks!

Theoretically it's possible, but expect a lot of issues on the way. For example you might have difficulties getting the external GPU connected via Thunderbolt while running Windows or Windows through Boot Camp. Further the hardware isn't cheap. You'll be able to buy a second Windows laptop capable of running the game with the same amount. If you have to invest to get it running, I'd definitely download the old Demo version first (it's still available for download, just search the web) and try to get it running on your system.
