Right ok by stating this is compared to a browser game may not be fair. Though we are talking about a large part of the new gaming industry talking billions. With "F2P" option you can play this game without a sub and pay for things you like. The only limiting thing I come up against is opening quests on a certain difficulty setting. Once again I dont actually play this game for free. Its extremely difficult for me to justify paying a sub just to open adventures on a certain difficulty setting.
