Really grabs your attention when you first play it, but after awhile gets a little repetitive.
One thing I do find an issue with though, is that begginner is to easy, and hard is annoyingly back and forth. An example is, you'll be fighting for a planet over and over again. At the drop of a hat, and there doesn't seem to be much rhyme nor reason, your enemies (or allies in some cases) will turn on you. This game is great that you don't have to micromanage that much, but there should be more description in the technology tree. Also, it takes longer for some technologies, which is never explained.
All in all, buy it, love it, resell it when you get bored. You'll play your money's worth on this one.
