I think that this is a average expansion pack to Empire Earth. This expansion has its up and downs. The gameplay is still the same with only a few things that are different. More units, civilizations, and three campaigns were added. However, this expansion offers little change in the original Empire Earth gameplay. The units added are pretty cool along with the other civilizations added. The Campaigns where a little bit short maybe its because I wanted more of Empire Earth. However, it still is good solid 10 hours of gameplay. Also a space age has been added which is pretty cool. However, for me this expansion didn't give me the same entertainment that I had got from Empire Earth. The storyline are well made but like in Empire Earth some of them are a little boring and could use a little bit of touch ups. The replay value is awesome even though you might not replay it single player, you defiantly want to go online with it and play again other people. This game is better then ever if you consider going online. The graphic are the same with little. I didn't notice any change expect some glitches are gone. So the graphics are improved a little. The sound effects are the same with few sounds add. I mean the sound quality is average and also could have been improved a little. I recommend this game to you if you absolutely loved the first one. If you love the first one then consider trying another RTS game.
