Skyrim is the game that refuses to die. Actually, Bethesda recently stated that millions of people still play it seven years after its first launch, so its little wonder that the king of open-world games on Steam is Skyrim. Skyrim is a phenomenal success in every sense of the word, presenting a massive open world that players can explore in any way they want.
