Another point of criticism has been the $10 price tag, which many gamers have said is too high. At that level, only 1 to 2 percent of people who download the game will buy the full version, according to Apptopia Inc. If the price was lowered to $2, it could likely convert more than 10 percent. The researcher estimates the lower price would translate into revenue of about $50 million for this month, versus about $30 million at the current price.
