Final Fantasy XI, you might have some problems with the way that the game's been handled over the years. Those problems are usually complaints about issues such as balance or the way that the game has handled updates, though, and they certainly don't extend to legal action. Yet back in 2009, Esther Leong filed suit against Square-Enix for fraudulent practices and deceptive advertising because of the game's monthly subscription fee. The claim was seeking over five million dollars in damages on behalf of all Final Fantasy XI players, which is probably a bit more than you seek when you feel your White Mage is underpowered.
The 9th District Circuit Court of Appeals has officially dismissed the case, ending its progression for good and establishing a precedent that most likely won't find itself under heavy contest. A deputy general counsel for Square-Enix had called the suit "baseless" when it was first filed, due in no small part to the game's transparent statement that players would be required to pay a subscription fee.
