The first Hunger Games took place in an Arena with 5 pinunsulas, each with a different habitat, Desert, Forest, Swamp, Field, and Mountains. The Cornocopia is at the end of the Forest Pininsula which reaches into the middle of the Arena. The Swamps are infested with Alligators, the Fields are infested with Tracker Jackers, the forest are full of poisinous plants, the Desert has daily sandstorms, and the mountains crumble very easily.
The ultimate winner was Piala from District Eight, ill post more info later
This was not reviewed in the book, but it is just roleplay.
