Grand Theft Auto (commonly abbreviated GTA) is a multi-award-winning video game series created in the United Kingdom by Dave Jones, then later by brothers Dan Houser and Sam Houser, and game designer Zachary Clarke. It is primarily developed by British developer Rockstar North (formerly DMA Design) and published by Rockstar Games. The series is set in fictional locales heavily modelled on American cities, while an expansion for the original was based in London. An open world is focused by Gameplay where the player can choose missions to progress an overall story, as well as engaging in side activities, all consisting of action-adventure, driving, occasional role-playing, stealth, and racing elements. The subject of the games is usually a comedic satire of American culture, but the series has gained controversy for its adult nature and violent themes. The series focuses around many different protagonists who attempt to rise through the ranks of the criminal underworld, although their motives for doing so vary in each game. The antagonists are commonly characters who have betrayed the protagonist or his organization, or characters who have the most impact hindering the protagonist's progress.
