I of the Dragon is a 3D action role-playing game with a twist - instead of a measly wizard or warrior, you play as a dragon. You must fly over large landscapes, killing monsters, destroying their lairs, and protecting the humans. There is also a strategy element: you must help humans build their towns. Your dragon can breath fire, ice, or acid, and cast a large variety of spells, including ones that can change the terrain. You will also have to eat regularly, as your dragon has a hunger meter that will deplete gradually until you eat either a neutral animal or a monster.
