Another major area of concern for software clones arises within China. From 2000 to 2015, the Chinese government had numerous restrictions on imports of hardware and software, and access to non-Chinese storefronts. While this allowed gaming on personal computers to flourish within China, the cost of acquiring both hardware and software was too expensive for many, leading to Chinese developers to create low-cost clones of popular Western and Japanese titles for the Chinese market, which persist today. Foreign companies are faced with difficulties in seeking legal action against the Chinese developers that have created these clones, making cloning a far less risky process. Thus, it is common for popular games from both Western and Japanese markets to see near-exact clones appear within China, often within weeks of the original game's release. A notable example is a clone of Blizzard Entertainment's "Hearthstone" called "Sleeping Dragon: Heroes of the Three Kingdoms" created by Chinese developer Unico, released within a few months of "Hearthstone" beta release. Blizzard was ultimately successful in suing Unico for in damages in 2014. In other cases, clones are made to address elements of the original game that are unsuitable under China's content restriction laws; for example, Tencent, which operated the publishing of "PlayerUnknown's Battlegrounds" in China, was forced to pull the game due to content related to violence and terrorism, and instead replaced it with a clone, "Game for Peace", which otherwise reused assets from "Battlegrounds" but removed blood and gore.
