Fantasy Earth Zero, then odds are good that you've also become a fan of the game on Facebook. (You can't escape from that site any more, really.) But if you do enjoy the game's hybrid of real-time strategy elements and fantasy battles without having become a fan of the game on social networking... you owe the Facebook fans a big "thank you." As a celebration for having reached 5,000 fans, the game is running a week of doubled experience.
Running from August 10th to the 17th, the effects are obvious -- every character will receive doubled experience, presumably from every source. While the game doesn't require high levels to be competitive in PvP, it does offer up more options. In addition, players who logged on between July 1st and August 9th will receive a few special in-game items as an additional thanks for playing. Another celebration is planned for 6,000 fans, so Fantasy Earth Zero players are encouraged to become a fan if you're not already.
