I have a weird confession. As GTA V has become more realistic, I play the game far too realistically. At red lights, I stop the car. I also have to make sure the protagonists commit crimes to their character ability. For example, I couldn't let Michael randomly hijack a car, whereas I could use Trevor for hijacking a car as his personality suits it.
I did that during my first few days of playing the game, I actually found it really helped me to get into the characters. Now I don't do it so much, but little bits stick with me. For example I listen to different stations with each character and I will only ever go on a rampage with Trevor,
