Japanese game company Square Enix has made massively multiplayer online role-playing games Final Fantasy XI and Final Fantasy XIV unavailable to play worldwide in an effort to conserve energy following last week's earthquake and tsunami.
The move follows Konami's decision to halt Metal Gear Online play.
Over the weekend the Japanese government asked householders to conserve energy in the hope it would help avoid power cuts across the nation.
Service on the two Final Fantasy MMORPGs was halted yesterday. The suspension is planned for at least a week. Final Fantasy XI's April service will be free as a result.
"Due to the continuous earthquakes occurring in the eastern regions of Japan since 11th March, the power companies in Japan have encouraged everyone to cooperate by conserving as much energy as possible as it is feared there will not be enough power supply," Square Enix said in a statement.
"Based on the current situation, we have decided to shut down the game servers temporarily, and therefore to suspend services of Final Fantasy XIV, Final Fantasy XI, and PlayOnline temporarily."
