I think it is worth playing, it has a great sense of style and humor. I remember the demo only showed a small part of gameplay, like just the basebuilding (with few options) and maybe you had to fend off an attack. In the full game you send henchmen out on a world map to get money and such, and there are traps and more aspects of the basebuilding to deal with. I bet it would not be too expensive for you since it is almost 2 years old now. And since you are burnt out I suggest you give it a try. If that sort of game interests you I think you will enjoy it.
