Sandbox

A Sandbox or Open World allows the player to roam freely in a massive world with considerable freedom in how or when to approach objectives. While Sandbox and Open world are used interchangeably, some like to use the terms to describe specific types of gameplay within the genre. Because these worlds are massive, time consuming, and potentially marked with filler quests, the term "Open World Fatigue" has come into use to describe player exhaustion in the genre.

Sub-themes
	Sandbox	Similar to a physical sandbox, the user is entertained by his or her ability to do as they wish creatively with "no right or wrong" way of playing the game. Some restrictions generally exist, either from the game environment, technical limitations, or in-game limitations. A large number of tools, abilities, and the freedom to experiment with them in creative ways is given to the player. The player is expected to invent their own fun with whats provided or try out new ways of playing within the playspace (game world) they have been given.	Example: The Elder Scrolls V: Skyrim Minecraft
	Open world	Features a more focused large world with a prominent story and characters. Gameplay tends to be structured, giving the player fewer creative options than a sandbox game in how they build/play their character or approach the environment. Everything is relatively defined; generally there is little to no room for the player to invent new ways of playing.	Example: Red Dead Redemption II The Witcher 3: Wild Hunt
	Overworld	A collection of interconnected "open" areas, usually towns, wilderness, or other locations. The player is sometimes able to travel on the world map, or uses the world map to select their next location. When the player enters one of the locations, the world map display may remain on the screen, be replaced by the local geography, or be hidden until the party exits the location.	Example: GreedFall Tales of Xillia
