Elex announced today that its Clash of Kings mobile game has hit 65 million downloads after a year on the market. Clash of Kings seems like a derivative title. Its name evokes Supercell’s Clash of Clans, the No. 1 top-grossing mobile game. And its gameplay isn’t all that different from Game of War: Fire Age. But its graphics are better, and the title seems to have a lot of growth in spite of those copycat appearances.
