Realism

Realism is something you find in real life AKA reality. Not in 'reality' shows or video games.

Honestly, don't start complaining about lack of realism in video games. Life isn't always fun, that's why only the fun parts were transported to video games. If video games WERE REALISTIC, I would never play them, ever.

Don't start complaining that video games belittle real world issues promote violence. War, combat, fighting and similar stuff are not 'fun' in the real world. Maybe for the real sick minority but not to most people.

So why are there so many games based on them? Because they give the player a sense of challenge, desperation and triumph without having to put yourself in danger. Online multiplayer components of these games appeal because they are rather like a sport, not because we love killing people.
