Pretty much exactly like this.
The fictional city of Los Santos in GTA V looks so much like LA that when the geniuses at Corridor Digital created this spectacular video entitled simply, “Real GTA,” their job was made that much easier. The accuracy of the depiction is unnervingly accurate, from the camera angles to the classic actions of carjacking and shooting gang members down in cold blood. Will there ever be a time when we will find it impossible to differentiate the virtual from the real world?
We're not there yet, but this GTA recreation proves we are certainly getting close.
