Thanks for the information! (and for reviving the topic)
Unfortunately I can no longer edit the post based on the new information, but I must state that I am interested in any future resurrection of this RTS. My most sincere apologies if I caused confusion to any reader of this topic
Thank you for the reply. I am interested in this RTS too. Unfortunately, after all these years nothing has come out. At least a similar game, “Rise of Nations: Extended Edition”, came out in 2014. But that was a remaster of an older game. I hope someday we will have a true new game of this kind.
By the way, there is a “strategy sale” at GOG.com right now, at which Empire Earth and many other strategy games are on sale. It is surely worth to take a look at it.
I would also like an EE remake, hopefully they decide to release the EE saga in extended version on Steam. What I remember most about EE is its excellent soundtrack and that there were practically several game modes (although I admit that it had complications with the infinite resources and the superpowers of the prophets ).
