It's really good city building game. It's not just a clone of other well established games but franchise with it's own ideas and original setting. That being said... It's a bit grim and depressing. Post-apocalyptic setting and hurdles thrown at the player can make you fill a little bit depressed. I know that other games of this type have some disasters to make their game little bit more interesting but this is different. So if you don't mind this kind of mood, go and play it.
