The honest truth is, this game is great for the casual gamer. Its very simplistic, and requires almost no effort to get through the game until the space travel portion.It *IS* a lot of fun, and one of a kind.However....The DRM sucks. They dont mention on the box, or their website, the simple fact that you will eventually NOT be able to run the game when they turn off the authentication servers. The DRM LIMITS you to 3 installs. That means I'll likely have to try and convince them that I deserve to have another install after reloading windows to get rid of virus's etc....and we all know THAT never happens.Awesome game. But the DRM problem outweighs any good benefits of the game.
