 and is given considerable freedom in choosing how to approach objectives. Video games that include such level design often are referred to as "free roam" games.

The term is sometimes used interchangeably with "sandbox" and "free-roaming"; however, the terms open world and free-roaming describe the game environment itself and allude more to the absence of artificial barriers, in contrast to the invisible wall
Invisible wall
An invisible wall is a video game term for a boundary that limits where a player can go in a certain area, but doesn't appear in-game as any kind of visible obstacle, or as an obstacle that in reality could easily be bypassed, such as a mid-sized rock or short fence...

s that are common in linear level designs. The term sandbox refers more to the mechanics of a game and how, as in a physical sandbox, the user is entertained by his ability to play creatively and with there being "no right way" of playing the game.

Despite their name, many open world games still enforce restrictions at some points in the game environment, either due to absolute game design limitations or temporary in-game limitations (such as locked areas) imposed by a game's linearity.

 or game designed as a nonlinear, vast open area with many ways to reach an objective. Some games are designed with both traditional and open world levels. An open world facilitates greater exploration than a series of smaller levels, or a level with more linear challenges. Reviewers have judged the quality of an open world based on whether there are interesting ways for the player to interact with the broader level when they ignore their main objective. Some games actually use real settings to model an open world, such as New York City

, the game's writers must find creative ways to impose a storyline on the player without interfering with their freedom. As such, games with open worlds will sometimes break the game's story into a series of missions, or have a much simpler storyline altogether. Other games instead offer side-missions to the player that do not disrupt the main storyline. Most open world games make the character a blank slate that players can project their own thoughts onto, although several games such as Landstalker: The Treasures of King Nole offer more character development and dialog.

Games with open worlds typically give players infinite lives

 refers to content generated algorithmically rather than manually, and is often used to generate game levels and other content. While procedural generation does not guarantee that a game or sequence of levels are nonlinear, it is an important factor in reducing game development time, and opens up avenues making it possible to generate larger and more or less unique seamless game worlds on the fly and using fewer resources. This kind of procedural generation is also called "worldbuilding", in which general rules are used to construct a believable world.
