This usually involves additional focus on the artificial intelligence and scripted behavior of computer-controlled non-player characters. Role-playing video games also typically attempt to offer more complex and dynamic character interaction than what is found in other video game genres. Often these attributes increase each time a character gains a level, and a character's level goes up each time the player accumulates a certain amount of experience. Players control one or several characters by issuing commands, which are performed by the character at an effectiveness determined by that character's numeric attributes. Role-playing video games typically rely on a highly developed story and setting, which is divided into a number of quests. RPGs rarely challenge a player's physical coordination or reaction time, with the exception of action role-playing games. A key feature of the genre is that characters grow in power and abilities, and characters are typically designed by the player.
Players explore a game world, while solving puzzles and engaging in combat. Players control a central game character, or multiple game characters, usually called a party, and attain victory by completing a series of quests or reaching the conclusion of a central storyline. Role-playing video games use much of the same terminology, settings and game mechanics as early tabletop role-playing games such as Dungeons & Dragons.
