"Choose Your Own Adventure" books were an easy way to feel accomplished as a child. In a few short, simple pages, you could make the decisions which would ultimately kill your character and you could count it as an entire book read — all the way through. Book that, Pizza Hut.
If you had more time to kill or wanted to go on another adventure, you could just crack the book open again and find a new way to die. Either way, you know how these books end.
The first step toward zombies.
You will either work with the President of the United States to force a surrender (while completely glossing over this blatant American violation of the 1972 Biological Weapons Convention) or join the terrorists in South America. All in all, the only decisions you make are really awful, just like the ones you make in real life. At least the cartels have free booze.
