There are two ways of going about this.
Realistic looking vs Stylized.
From a logical standpoint i'd say if you're going for something realistic then it needs to present itself in a more solid and fashionable tone. Take a racer for example, need for speed or project cars both hit the nail on the head. It gives you a rush because it looks real(ish), you associate yourself in that car and in some cases you get a rush from a game because you think it's real, you forget about the outside world if you want to go to the extreme.
Stylized racers go for a more casual laid back experience, you play to kill time essentially.
