This is a strategy game, one of the few games that have been released that are decent strategy games. I dislike this game, I wouldn't recommend it, but it is one of the better strategy games that have been released in the last couple years. I like that it tried and wasn't a massive waste but it could have been much better and other developers are making better games then this and are free.
I would only buy this game if you are a die-hard strategist (like myself), but keep in mind that there are better games than this one out there.
