You are the Gamemaker and you design the whole arena! Things you can add are: Trees Mountains/Hills Flowers Mutts Cornucopia, that when stamped, starts The Hunger Games Backgrounds When the games start, adjust the brightness with the toggler (Toggle with arrows)
Thx to HungerGames21, HungerGames117 and UnprovenTheorem. The Game isn't fully ready, as you may see. After you put down the Cornucopia, the games will start, allowing you to dictate a Hunger Games.
