Why are all rpg games based on World Of Warcraft crap?

Seriously Normal rpg games like cops and robbers or Zombie rpg games are dieing. Why are all games based on World Of Fuckcraft. Who cares about magic rpg crap that game was made over 1000 times. When i type in google rpg i get wow similar games with swords and magic and all that **** at once. Why people cant make post apocalyptic or real life rpg ? I am sure you people all agree with me. I dont know why are rpg makers so freaking stupid. They just randomly make a wow game and hope they get cash. I think they would get cash if they make some kind of apocalitpic or some good fps rpg searching for food etc. So question is WHY?
