In a bold legal move, Sony has filed a lawsuit against Tencent, claiming that its upcoming game, Light of Motiram, is a “slavish clone” of its acclaimed Horizon series. The lawsuit, lodged in a California federal court, accuses Tencent of copyright and trademark infringement, asserting that the similarities between Light of Motiram and the Horizon games are so pronounced that players could easily mistake the two as being part of the same franchise.
