据developerAnalytics和Wedbush Securities研究数据显示facebook前十大社交游戏开发者的月活跃用户表现持续疲软。继9月份微跌2.2%之后，十月份再度暴跌7.4%。从下面的图标可以看出在最近的6个月当中，只有八月份表现增长（学生假期），其他的五个月份都有不同程度的下跌。

据secondshares文章称facebook这些开发者的用户数据暴跌可能也不奇怪，这个季节刚好是学校的开学季，很多学生用户和他们的家长特别是母亲的大部分精力都转移到学校方面了。

从4月份facebook推出新政以来，这10大顶尖游戏开发者的月活跃用户数已经跌去14.3%的份额了。（增长的扣去减少的量）

在这些顶尖的社交游戏开发者当中，只有CrowdStar逆势增长，月活跃用户的整体表现甚至超过了EA和playdom，而仅次于zynga。另外Digital Chocolate也出现了大幅度的用户数据攀升。

如果具体到单一的游戏而言，zynga旗下的farmville从高峰期的8320万,AU跌回5640万MAU，跌幅达32.2%；zynga旗下的另外一款游戏petville跌幅更是达到了54%；CrowdStar的一款游戏happy acquarium也跌去了52.7%的用户。

在前11大社交游戏当中其中跌幅超过有7款，整体跌幅达到了33.4%。（从4月份到现在）（本文由游戏邦/gamerboom.com编译）

After a 2.2% decline in MAU’s in September for the top 10 Facebook game developers we track, October MAU’s dropped by 7.1% to 403.2 million.  A drop in MAUs in October is not surprising, given it’s the first full month of school, sucking up the time of both students and their moms.  But given the size of the drop, we also believe that game fatigue is a factor.   Since Facebook starting ratcheting back viral marketing by the gaming companies last April, MAUs have fallen in 5 of the last 6 months and are down 14.3% since their April peak.

The four largest developers when we started tracking the social gaming sector in April are still the four dominant players; however, CrowdStar is the only company to experience MAU growth since April, largely due to the success of Quiz Planet and its 16mm MAUs.    Digital Chocolate has sky rocketed up the charts due to the success of Millionaire City, introduced in May :

Looking at the stats by game, Farmville, the granddaddy of social gaming hits, is still more than 50% bigger than the #2 game, but has lost over 32% of its audience since peaking last April, which is slightly better than the average decline of 33%.  However, several games, most notably Texas Hold ‘Em and Mafia Wars, have bucked the trend, maintaining or even growing their audiences over the six month period we’ve been tracking social games.   Digital Chocolate’s Millionaire City is still growing, having launched in late May.（source：secondshares）
