Which came first Star Wars battlefront or Star Wars 2 andit was Star Wars battlefront it came out previously then the Star Wars 2

By "star wars 2" I'm assuming you meant the movie, Star Wars Episode II: Attack of the Clones. After the release of Attack of the Clones, Star wars Battlefront came out. The game utilized designs, concepts, and locations from the movie, as well as the pre-existing movies. The same happened for Star Wars Battlefront II, as it was released after the release of (the movie) Star Wars Episode III: Revenge of the Sith
