Thematically, it's about the very simple idea that, in this postmodern world of ours, human beings—all of us—are worth less. We're worth less every day, despite the fact that some of us are achieving more and more. It's the triumph of capitalism. It's the triumph of capitalism over human value.
The player in GTA4 has so many options. Not just options within the single player game but also the chance to play in multiplayer mode, within which there are several ‘mini-games’ such as ‘Cops and Crooks’, ‘Hangman’s Noose’ and ‘Mafiya Workout’.
It was in the gameplay itself where Grand Theft Auto managed to break the mould in many ways.
