华纳兄弟互动娱乐近日成功为旗下两款游戏，《中土战争：暗影魔多》及续作《中土战争：战争之影》中的「复仇系统」申请到专利。该系统的特点为：某个派系的 NPC 会记住玩家的行为并对此做出反应，且他们的反应会进一步影响派系内其他 NPC 的行动。一言蔽之，一个显著的例子是，你杀死兽人和兽人杀死你都会对后续游戏世界和玩法产生影响。美国专利商标局的官方公告中写明，华纳兄弟互动娱乐申请的专利名为“电子游戏中角色、军队、族群的复仇系统”。该项目将于 2 月 23 日起生效，专利有效期至 2035 年。华纳兄弟从 2015 年开始就为此申请专利，但被多次驳回，理由为该系统与其他已申请的专利相似点太多，但这都已经成为了过去式。专利生效前暂且不论，2 月 23 日后，如果有开发者希望制作一个与专利描述极为相似的复仇系统（或者是足以被
