@eshenk Is simple, is a game, mean for entertaiment. GTA V is based in a cartoonished style, just see the peds, the proportions, the vehicles, the world variations, etc. Everything is just a big scenary for a parody about social problematics in the world. For real life simulators, nothing is so real like open the door and take a passage along the cities.
Now, why do mods unrealistic, fantastic or surreal? For the same reasson to see a movie, read a book, listen an history in a song, we need the experience of no possible things, see them at least. The real life can be tragic and bored, but in videogames you can have a Maserati in your garage or fly or use anormal clothes, etc lots of options in a trainer to modify your virtual life and not following the wishes of game developers (you know, GTA V single player mode is a boring experience without mods, totally abandoned by developers). Mod means modifications, you can personalize your game, but no all people wants to live a photorealistic gaming experience to take a bus, go to job and return to home in a videogame.
