标题： I Would Not Plant Apple Trees If the World Will Be Wiped: Analyzing Hundreds of Millions of Behavioral Records of Players During an MMORPG Beta Test

摘要： 在本工作中，我们使用MMORPG ArcheAge封闭测试期间的玩家行为作为极端情况的代理：在封闭测试结束时，所有用户数据都会被删除，因此玩家在最后几天内的游戏行为的结果（或惩罚）失去了意义。我们分析了ArcheAge第四次封闭测试中的2.7亿条玩家行为记录。我们的研究结果表明，没有明显的流行行为变化，但一些异常值更可能表现出反社会行为（例如，玩家杀人）。我们还发现，与“即使我知道世界明天就会崩溃，我仍会种植我的苹果树”的安慰性说法相反，玩家放弃了角色进展，在测试结束时任务完成、升级和能力变化急剧减少。 显示英文摘要

摘要： In this work, we use player behavior during the closed beta test of the MMORPG ArcheAge as a proxy for an extreme situation: at the end of the closed beta test, all user data is deleted, and thus, the outcome (or penalty) of players' in-game behaviors in the last few days loses its meaning. We analyzed 270 million records of player behavior in the 4th closed beta test of ArcheAge. Our findings show that there are no apparent pandemic behavior changes, but some outliers were more likely to exhibit anti-social behavior (e.g., player killing). We also found that contrary to the reassuring adage that "Even if I knew the world would go to pieces tomorrow, I would still plant my apple tree," players abandoned character progression, showing a drastic decrease in quest completion, leveling, and ability changes at the end of the beta test.
