如标题所示，最后一块多米诺骨牌也砰然倒下了。最近，社交游戏公司Playdom也最终屈服于Facebook，同意使用Facebook Credits作为其虚拟货币。但幸运的是Playdom公司仍然接受信用卡，借记卡和Paypal等支付方式。

如果与此前Facebook同其他公司签订的合约一样，那么未来Playdom销售虚拟商品获得的Facebook Credits收益也被Facebook社交网站瓜分走30%。但值得一提的是Playdom旗下游戏Social City中的虚拟货币City Bucks和游戏ESPNU College Town 中的Campus Cash并不会被抽成，另外Playdom广告合作商提供的免费虚拟货币也幸免于难。

Playdom - Social City

这并不是Facebook首次强迫社交游戏开发公司使用其新虚拟货币Facebook Credits。目前这款虚拟货币可见于GameStop和Radio Shack多家主要商店。继CrowdStar和Zynga公司纷纷屈服于Facebook，相信EA和Playfish最后也将和Facebook签下类似条款。最终，Facebook公司将可以通过Facebook Credits从四大主要社交游戏公司瓜分30%的利润。让我们默哀片刻，现在我们知道为什么Zynga急于摆脱Facebook了。（本文为游戏邦/gamerboom.com编译，转载请注明来源：游戏邦）

Just like that, the final domino falls. Playdom is the next company to submit to Facebook’s demands for social game and app developers to accept only its virtual currency. As of today, Playdom will only be accepting Facebook Credits as its virtual currency. Fortunately, the company will, of course, still accept credit and debit cards as well as PayPal payments.

If this deal is anything like Facebook’s previous three, we imagine Playdom will have to deposit 30 percent of all Facebook Credits sales into the social network’s bank account. It also bears mentioning that the unique currencies to Playdom’s games like City Bucks in Social City and Campus Cash in ESPNU College Town aren’t going anywhere; it’s the third-party payment methods that are officially kaput. And thankfully the free offers from Playdom’s ad partners for in-game money don’t seem to be going anywhere either.

This isn’t the first time Facebook has coerced social game companies into using its new currency, which is now available at GameStop and Radio Shack in addition to nearly all major department stores. With CrowdStar the first to go and later Zynga giving in, it was only a matter of time before EA and Playfish accepted the offer too. Finally for Facebook, the company will be reeling in 30 percent of the top four social gaming companies’ profits via Facebook Credits. Let that one sink in for a while and you’ll understand why Zynga might want out. （Source：Games.com）
