A simple fetch quest turns into a forgotten childhood memory. The single-best overview of the amount of technical effort and calculation behind every frame of Grand Theft Auto V is probably http://www.adriancourreges.com/blog/2015/11/02/gta-v-graphics-study/ - while others are out there, the use of a single frame of the game (that calculates 60 frames per second) lets you look at all the subsystems and choices made to make the system run. If that's not deep enough for you, may I suggest Miriam Bellard's explanation of baking story and meaning into architecture in GTA V: https://www.gdcvault.com/play/1025736/Environment-Design-as-Spatial-Cinematography
