Open world games

An open-world video game is a genre of video game where the player is given a large, expansive virtual world (or universe) to explore and interact with. In contrast to linear games that follow a predetermined path or level-based progression, open-world games typically offer freedom and non-linearity, allowing players to roam and engage with the game world at their own pace.

Open-world games often feature vast landscapes or cities that can be freely traversed, and they often include a variety of activities, missions, or quests for players to undertake. These games commonly provide a range of gameplay options, such as exploration, combat, puzzle-solving, character development, and interacting with non-player characters (NPCs).

Popular examples of open-world games include The Elder Scrolls series (e.g., Morrowind), the Grand Theft Auto series, Ultima 7, Darklands, and Star Control 2, among many others.
