Having acquired OpenFeint over a year ago, developer, publisher, and mega-company GREE has kept their cards pretty close to the chest regarding their plans for the technology. Until today. In a formal announcement sent to Gamezebo, the multinational mobile-social gaming giant marked May 23rd as the kick-off for the GREE platform. Also known as? World domination, phase B.

At just 27 years old, Jason Citron carries quite the resume. He helped develop DoubleFine’s Brutal Legend in 2006. He released his 2008 iPhone game Aurora Feint on the day that the App store opened. Then, in 2011, he sold his social gaming network OpenFeint to GREE for a whopping $104 million. With so much success at such a young age, the question over the past year has remained: What will Citron do next?

File this one under “should’ve seen it coming.” Earlier this year, GREE acquired Openfeint for $104 million. Or to put it another way, one of Japan’s largest mobile social gaming companies acquired one of America’s largest mobile social gaming companies for $104 million. Well surprise surprise – this newly formed international superteam have just announced the creation of a new worldwide mobile social gaming platform for 2012.

Who says you can’t make money on Android? Papaya Mobile, a mobile social networking platform for Android phones, announced that it has grown to 25 million users, up 940% since January 2010.

Of course, the majority of gamers for Papaya’s social mobile games are not paying a penny, but the ones who are are paying relatively more than what one would see on other social networks such as Facebook.

The average revenue per paying Papaya user is $22.60 a month and there have been 11 million transactions with Papaya’s virtual currency.

As popular as freemium games on Facebook and mobile are, it’s always amazed us that so few developers have tried to make the jump between the two. Sure a handful of games have done it like It Girl, FarmVille, and Buddy Rush, but these seem to be the exceptions that prove the rule. As it turns out, we weren’t the only ones puzzled by this situation. The folks at OpenFeint have been pondering the same thing, and they’re looking to do something about it. The company has just announced the hire of Ethan Fassett, a former Playdom executive, to spearhead an initiative to bring Facebook developers to mobile.

Thanks to leaderboards and achievements, social gaming networks like Apple Game Center thrive on the idea of competition. But there’s always been one problem – it’s a spirit of competition you’ve had to seek out on your own. The challenges never came directly to you. Now OpenFeint is looking to change all of that with that announcement of their latest addition, GameFeed.

Only days after their acquisition by Japan’s social gaming giant GREE, OpenFeint is already making their presence known in the East. How so? By powering The9 Game Zone for 800 million mobile users in China.

When you get as big as you can at home, it’s time to go international. That certainly seems to be the case for OpenFeint. Arguably the biggest player in the US mobile social gaming market, they’ve just been acquired in a triangular merger by GREE, a mobile social company of similar standing in Japan.

It’s a pretty lofty claim (and a totally false one, since I can’t use OpenFeint on my toaster), but the folks behind OpenFeint have just announced that their latest initiative will allow for social gaming on any device you can think of – and we’re not just talking handhelds anymore.

Football fans around the country are gearing up for the NFL’s biggest game of the year (and if speculation about a players strike comes to fruition, it could be the biggest game of the next two years). PikPok, the developers of Flick Kick Field Goal, want you to kick off the championship weekend with a bang.
