User-Generated Content (UGC) refers to any form of content, such as posts and images, created by users rather than by professionals. In recent years, UGC has become an essential part of the evolving video game industry, influencing both game culture and community dynamics. The ability for users to actively contribute to the games they engage with has shifted the landscape of gaming from a one-directional entertainment experience into a collaborative, user-driven ecosystem. Therefore, this growing trend highlights the urgent need for summarizing the current UGC development in game industry. Our conference paper has systematically classified the existing UGC in games and the UGC editors separately into four types. However, the previous survey lacks the depth and precision necessary to capture the wide-ranging and increasingly complex nature of UGC. To this end, as an extension of previous work, this paper presents a refined and expanded classification of UGC and UGC editors within video games, offering a more robust and comprehensive framework with representative cases that better reflects the diversity and nuances of contemporary user-generated contributions. Moreover, we provide our insights on the future of UGC, involving game culture, game genre and user creative tendencies, artificial intelligence, its potential ethical considerations, and relationship between games, users and communities.

翻译：用户生成内容（UGC）指由用户（而非专业人士）创建的任何形式内容，如帖子与图像。近年来，UGC已成为不断发展的视频游戏产业的重要组成部分，深刻影响着游戏文化与社区生态。用户能够主动参与其体验游戏的创作，这一能力将游戏领域从单向娱乐体验转变为协作式、用户驱动的生态系统。因此，这一日益增长的趋势凸显了对游戏产业当前UGC发展进行系统性总结的迫切需求。我们先前发表的会议论文已分别将游戏中现有UGC及UGC编辑器系统划分为四种类型。然而，既有综述在深度与精确性上尚不足以涵盖UGC广泛且日益复杂的本质。为此，本文作为前期工作的延伸，提出了一套经过优化扩展的视频游戏UGC及UGC编辑器分类体系，通过代表性案例构建了更严谨全面的分析框架，以更准确地反映当代用户生成内容的多样性与细微差异。此外，我们针对UGC的未来发展提出见解，涉及游戏文化、游戏类型与用户创作倾向、人工智能技术、潜在伦理考量，以及游戏、用户与社区间的多维关系。
