It's rather daunting at first when your scout discovers enemies with crazy high power. But like any well thought out game, there is a plan which comes together.
I was thinking of saying that it's simple, but that's not the right word. It's not overly complex, the way many games of this genre are. There is a clear end in sight with a choice of paths to get where you're going.
And I know it's an idle game, but I've had it open on my PC for two or three days now I'm and about half way to my first billion power.
Great fun :)
