There are two types of player characters in games: those controlled by human players and those controlled by computers. The first type is known as a player character while the other type is referred to as a non-player character. Player characters can be almost anything you can imagine. In modern games, player characters are usually human or humanoid. This is not to say you cannot create a game in which the player character is an uprooted tree or a rock with seven legs. For our game, the player character will be a human boy named Colt.
