LOLapps has announced that they will be releasing Ravenstone Mine, an expansion to their Ravenstone Fair. The social game designed in part by John Romero has already accumulated 10 million monthly active users.

“We are using a traditional strategy in games,” said Arjun Sethi, chief executive of San Francisco-based LOLapps, in an interview. “Instead of focusing on how much money we can make from a user, we are focusing on how long we can hang on to that user. Here s a new world that interacts with the one the user has been spending a lot of time in.”
