知名社交游戏开发商CrowdStar日前宣布将遵循facebook的虚拟交易规则，达成5年期的战略合作伙伴关系。这是继zynga之后大型社交游戏开发者与facebook达成的第二笔协议。

尽管在知名度上和zynga不在一个档次上，据appdata的统计数据，CrowdStar目前仍然是facebook月度活跃用户排行榜上位居第五。传言很多投资商对CrowdStar充满兴趣，微软就是风传的买家之一。

CrowdStar旗下有五大相当出名的游戏，分别是hello city、happy aquarium、happyisland、zoo paradise和happypet。其中happy aquarium一度成为facebook上水族馆类的佼佼者。

CrowdStar, the big social game developer, says it will use Facebook’s virtual currency system in all of its games under a “five-year strategic relationship.” The startup is the second major social games maker to commit to using Facebook Credits, which the social network has been slowly rolling out. Last month, Zynga said it would expand use of the system in its games, although, unlike CrowdStar, it did not specify it would use Facebook Credits exclusively.

Although lesser known than Zynga, CrowdStar—which is behind titles like Happy Aquarium—is growing rapidly and is now the fifth largest game developer on the social network by monthly active users, according to AppData. That growth has attracted interest from investors, and, earlier this year, Microsoft (NSDQ: MSFT) was reportedly in talks to buy the company.

CrowdStar began using Facebook Credits in December, and in a statement, the company says the average revenue it earns per customer has increased by almost 50 percent since then, which it says reflects “the increased level of comfort and trust that customers have when buying currency from Facebook.” Some developers, however, have balked at the 30 percent cut of revenue from Facebook Credits that the social network takes.
