I interpreted it more about its game design – GTA is about a giant sprawling city come to life as an interactive playground, one way you can think of it is most genres of games are represented within it. (Story game, single player, online semi MMO, anarchy sandbox simulator, life sim, racing, deathmatch shooter, gambling game, sports game, Crazy Taxi, flying, etc.) But that also means fans of those individual genres looking mainly for that specific experience within it will be disappointed by the lack of depth or richness compared to games that focus purely on that one genre vs all at once. That said this is probably the most expensive game ever made, so they are also able to invest surprising depth into each of these 'genres' despite it all. And I guess that is one reason why GTA V (previous in the series) has sold something like 150 million copies – it's a very different game to many groups of these customers but still satisfying.
