Chinese gaming giant Tencent pitched Sony on making a Horizon mobile game, one that would have expanded the world of the franchise to Asia and included multiplayer and games-as-a-service elements, according to court documents.Details of the pitch are included in the recent lawsuit Sony filed against Tencent, alleging Tencent's upcoming open-world game Light of Motiram to be a copy of Sony's Horizon franchise. Sony claims in the lawsuit Light of Motiram is infringing on Sony's copyright and trademarks, and is seeking to prevent the game from being released.In the documents, Sony outlines how in March 2024, Tencent and its Aurora development studio approached Sony about developing a new Horizon mobile game with a pitch deck titled "Expanding the Horizon." The game would have expanded Horizon's world to include Asia, with a slide from Tencent's pitch included in the lawsuit stating how Horizon heroine Aloy would receive "an invitation from the mysterious Orient" and travel to a "distant kingdom."An image showing Aloy atop the Great Wall of China is also shown. The game would have introduced new tribes "inspired by ethnic minorities," according to one slide, as well as Eastern-inspired aesthetics and new "mechanimals" inspired by Eastern mythology, with a piece of concept art showing a mechanical Chinese-style dragon.According to Sony, the Aurora Studios team proclaimed to be "die-hard fans" of the franchise, and presented screenshots of team members' PlayStation Trophies earned while playing Horizon games and an image of the development team playing Horizon at their studio. Tencent stated the Horizon franchise's popularity in China and its open-world RPG setting showed potential as a GaaS (games-as-service) mobile game. Tencent also suggested incorporating survival-crafting elements, pet taming, and multiplayer modes, according to the lawsuit.Sony states that during the pitch meeting, Tencent did not disclose it was already working on Light of Motiram. According to the lawsuit, Sony rejected Tencent's Horizon pitch in April 2024, stating that while it "greatly appreciated Aurora's level of passion and the effort put into the pitch," it would not be pursuing the partnership.When Tencent did announce Light of Motiram in November 2024, Sony states in the lawsuit that its gameplay trailer did not feature any of the "Eastern-inspired clothing, aesthetics, and backdrops that Tencent pitched and instead copied Horizon whole cloth."Sony is seeking statutory damages of up to $150,000 per "each separate work in the Horizon franchise infringed" as well for Tencent to hand over all products and marketing materials that bear "prohibited marks" so that Sony can destroy them. Light of Motiram remains available to wishlist on Steam but does not have a release date.
