Good game - who doesn't like nuking the crap out of someone?
However, the online multiplayer is dead. It is really hard to find a match, and when you do nobody ever speeds it up. The best part of this game is mulltiplayer (Just like Civ) because, at least in my mind, it is way more fun playing with a person you can actually talk to and strategize against - and maybe even ally with. The computers (or should I call them mindless drones?) will never befriend you, always act the same, and it always feels the same.
I personally think that it would be way better if more people played. However, the game is still fun, even in sungleplayer.
Due to the deep strategy you (may) be able to incorporate in singleplayer or multiplayer, it is still a good game. More of a timekiller for me, but if I find a match its on.
I still have to recommend - maybe more people will start playing multiplayer sometome.
