最近，社交游戏开发公司Booyah为提高玩家游戏时间和建造更多样化的虚拟俱乐部对旗下热门Facebook游戏Nightclub City进行了一系列调整。

Nightclub-City

首先，Booyah移除了能量条游戏机制。添加于今年10的能量条功能在Frontierville和It Girl也有出现，玩家在游戏中进行各种活动都会消耗一定的能量。一旦当日的能量耗尽，玩家要么选择买能量，要么就只能慢慢等候系统回复能量。根据Appdata数据显示，社交游戏Nightclub City在12月中旬最高峰期月活跃用户达858万，日活跃用户达127万。然而之后月活跃用户迅速下降至492万，而日活跃用户也下降至57万6000。此前，在Booyah引入能量条游戏机制之前，Nightclub City就已经出现了下滑趋势，而能量条机制的引入也没有实现流量的提升。

近来，随着游戏玩家投入越来越多的时间，不少游戏开发商们也放弃了能量限制。

其次，Booyah拓展了游戏中的俱乐部理念。此前，玩家再游戏虚拟世界中只能经营一家俱乐部。现在，玩家们可以另辟疆土啦！玩家的新俱乐部将从0级开始经营，努力向五星级迈进。

另外据游戏邦了解，Nightclub city游戏在4月发布之初就融入了强大的音乐阵容，最近Nightclub city还在itunes发布了游戏音乐专辑。本月，乡村歌手Keith Urban的新专辑中也有5首新歌出现在游戏中。此外，《电子世界争霸赛（Tron）》新电影也在Nightclub city开展了一些列宣传活动。

对此，Booyah交流总监David Diaz表示Tron的现在宣传活动已吸引了近200多万Facebook页面Likes，相信明年首季度会有更多娱乐界知名人士关注该游戏。（本文为游戏邦/gamerboom.com编译，转载请注明来源：游戏邦）

Booyah has made a series of changes to its hit Facebook game Nightclub City, with the overall goal of letting users play more and create a wider variety of virtual clubs.

The company is removing Energy, a game mechanic it added in late October that, similar to what you’ll see in games like FrontierVille and It Girl, made all activities cost either time or money. Once a player had used up their Energy for the day, they either had to buy more or wait to recoup their virtual strength. The game grew to a peak of more than 8.58 million monthly active users and 1.27 million daily actives by the middle of December, according to our AppData tracking service, but it has since fallen to 4.92 million MAU and 576,000 DAU. The decline happened before Energy was introduced, but the mechanic hasn’t helped boost traffic numbers.

As social gamers play longer and longer sessions, we’re interested to see if more developers cut back on energy-type limitations.

The other big change — and one that could send those numbers back up — is an expansion of the club concept. Up until this point, you could only have one main club in a given virtual city location. Now you can add an additional one. Each new club will start with a zero rating, and you’ll need to work your way up to five stars. But, with more locations you can through multiple parties at once, allowing you to make more virtual money more quickly.

Nightclub City has had a strong lineup of songs for its soundtrack since it launched in late April — to the degree that it’s also releasing a compilation album on iTunes today — but it’s also been adding bigger names in entertainment, too. Country star Keith Urban provided five tracks from his new album to go along with the game’s addition of a Western theme earlier this month, and in a move beyond music, the new Tron movie also has its own venue. Users can watch trailers for the movie, and the accompanying video game, and gain access to more items.

Booyah head of communications David Diaz tells us that promotions have already generated 2 million Likes on Facebook. Look for more big-name entertainers to come to the game in the first quarter of next year — as well as more products from the company.

We named Nightclub City the #1 new title of 2010, back in the middle of the year (we’ll be providing our year-end take on the industry later this month). The changes today appear to point the game in the right direction, and we’ll be watching for the results. （Source：Inside Social Games）
