From the risks section: We rely on a small percentage of our players for nearly all of our revenue. A small percentage of our players account for nearly all of our revenue. We lose paying players in the ordinary course of business. In order to sustain our revenue levels, we must attract new paying players or increase the amount our players pay. To retain paying players, we must devote significant resources so that the games they play retain their interest and attract them to our other games. If we fail to grow or sustain the number of our paying players, or if the rate at which we add paying players declines or if the average amount our paying players pay declines, our business may not grow, our financial results will suffer, and our stock price may decline. Is this normal in the social games industry?
