Liberty City is one of the most iconic settings in Grand Theft Auto, as it is the sandbox in which Grand Theft Auto 3 catapulted the franchise into global popularity. Rockstar Games returned to the scummy city in Grand Theft Auto 4, a title that garnered a mixed reaction from fans at launch. Though its themes and gameplay may not have resonated with the entire fan base then, Grand Theft Auto 4 would go on to become a landmark title, thanks in part to its use of the RAGE engine.
