This game is truly great!
The single player on this game is done well by ES. The AI difficulty levels are well set and it is easy to get a game started, with all the right components, very quickly. There is a wide enough variety of maps available, so there's something for almost every mood.
The campaign is also done well, with 31 scenarios and an addictive storyline. When I started playing the campaign, the story was good enough that I didn't want to stop! And that, for a game, is unusual in itself. The campaign utilises all the features that you get in the single player, as well as some only available in the editor. The rich cinematics also add to the atmosphere, making this a remarkably good addition.
The multiplayer steps up a great deal from Microsoft's Zone, which was used in the previous 'Age' games. I find it easy to use, and there's always some action available for us fans to enjoy! There are few errors, and lag is kept to a minimum.
Overall, this game really does bring together all the features that you could want in an RTS game. The explosive action will really keep you coming back for more. A brilliant piece of design and engineering.
