The reason for this was Rockstar’s signature scrupulous approach by game makers to detail. The main paradox of Grand Theft Auto 4 is that the notorious realism did not make the game boring.
Now you will not meet the military on tanks, bicycles have been abolished along with radio-controlled cars, onlookers in the streets behave differently muttering under their breath or chatting among themselves, and in the morning the city’s streets are covered with dense fog. The peculiarity of GTA 4, in the first place, is that the game has taken the path of realism, albeit not in all its glory. We still have to study the streets of the next metropolis, this time sketched from New York, perform both plot and secondary tasks, drive on cool cars, participate in shootouts, in a word, do everything the same as before, only on new way. In other matters, the idea of gameplay has not changed. Thanks to Grand Theft Auto IV, the franchise received a completely new life, as the game went towards realism, while preserving the arcade features and a certain cartoony character of what is happening.
Grand Theft Auto 4 - is an example of the correct evolution of a series of video games.
