Free-to-play and in-app purchase business models on mobile have changed the gaming landscape – thanks to a new segment of mass market casual gamers, proliferation of connected devices and revolution in digital distribution.  In this new world, monetization now depends on engagement, retention and driving micro-transaction purchases.

This panel, “Making succesfull free-to-play and in-app purchase driven mobile games,” addresses the challenges and opportunities head on from the point of view of the studio, and is made up of successful free-to-play and in-app purchase mobile game studio leaders, who have learned from trial-and-error, constant measurement and relentless iteration.  The panel discussion is led by Jeferson Valadares, a veteran studio exec who has held various senior production roles at Playfish, EA Mobile and Digital Chocolate.

Each year, GamesBeat follows a big trend. In 2009, we focused on how All The World’s a Game, with the explosion of games onto a global stage. Last year, GamesBeat@GDC focused on Disruption 2.0. This year, our theme is Mobile Games Level Up, and it focuses on the busy intersection of games and mobile technology. We’ll focus on everything from smartphone games to tablets and handhelds.

Console games dominated the news in the past, but the center of attention is rapidly shifting toward mobile as more and more users play games on the run. While there are hundreds of millions of gamers on Facebook, analysts believe the number could be much higher for mobile games. Our speakers are right at this intersection of gaming and mobility. GamesBeat 2011 targets an audience of CEOs, executives, entrepreneurs, investors, marketers and other key figures in the game business. Stay tuned for more speaker announcements.

We’ll be exploring the most disruptive game technologies and business models at our third annual GamesBeat 2011conference, on July 12-13 at the Palace Hotel in San Francisco. It will focus on the disruptive trends in the mobile games market. GamesBeat is co-located with our MobileBeat 2011conference this year. To register, click on this link.
