Expect to be able to get a free copy between 12 December at 11.00 GMT and Wednesday 14 December at 10.59 GMT according to GOG.com (I still like to call it Good Old Games). This is a nice opportunity to get the game for free before the offer expires. :P
While I'm aware of Empire Earth II (yes, I played that one too in demo form); at least ya can enjoy the original for those who do not possess it at this time.
I will provide the link to GOG right here for those who have not heard of it:
