GTA IV Era
The Grand Theft Auto IV Era refers to a current and ongoing canonical era of Grand Theft Auto games. These games are grouped together mainly because they have interlinking characters, storylines, and locations, specifically GTA IV's rendition of Liberty City and the state of Alderney. This is also known as the fourth generation of GTA games released from 2008 to present.
