In some games, the player's representation is fixed, however many games offer a basic character model, or template, and then allow customization of the physical features as the player sees fit. For example, Carl Johnson, the avatar from "", can be dressed in a wide range of clothing, can be given tattoos and haircuts, and can even body build or become obese depending upon player actions. One video game in which the avatar and player are two separate entities is the game "Perspective", where the player controls both themself in a 3-dimensional world and the avatar in a 2-dimensional world.
