Graphic adventures are adventure games that use graphics to convey the environment to the player. Games under the graphic adventure banner may have a variety of input types, from text parsers to touch screen interfaces. Graphic adventure games will vary in how they present the avatar. Some games will utilize a first-person or third-person perspective where the camera follows the player’s movements, whereas many adventure games use drawn or pre-rendered backgrounds, or a context-sensitive camera that is positioned to show off each location to the best effect.
