Concerto Gate (コンチェルトゲート, Koncheruto Gēto) is a massively multiplayer online role-playing game developed by Ponsbic and Square Enix.

The battle style is a mixture of a turn-based and real-time, similar to the Final Fantasy series' ATB system, and enemies are found as random encounters.

[1] Combat takes place on a ten square grid, choosing a combination of physical attacks and ranged spells.

[7] In October 2007, Square Enix announced that Nexon would publish the game in North America, doing a public beta in the first half of 2008, with release in December 2008 by OnNet.

[12] Since it was made in conjunction with Ito, Kikuta found it difficult to write the last two songs to complete the album and tie it together musically.

[12] Joystiq praised Concerto Gate for attempting to bring the excitement and frustration of the random battle system to an MMORPG.
