Grand Chase

Grand Chase (Korean: 그랜드체이스, lit. Grand Chase) was a free-to-play, two-dimensional side-scrolling MMORPG developed by the South Korean company KOG Studios. Alternative names for Grand Chase include 3小俠 (Three Young Heroes) used on the Taiwan server but was changed to 永恆冒險 (Eternal Adventures). Another name used was 彩虹骑士 (Rainbow Warriors) on the Mainland Chinese server. The reopening of the server also used the name of the Taiwan and Hong Kong server.

As of April 15, the game ceased development and terminated its service worldwide, with North America being the last foreign server to close in 2015. The mobile sequel Grand Chase Dimensional Chaser was launched in January 2018.

Grand Chase was awarded as Indonesia's most popular online game in August 2011 and has spawned several spin-off games such as Grand Chase Lite and Grand Chase M. It was also considered as the national online game of Brazil.

Elsword, another game developed by KOG, was regarded as the spiritual successor to Grand Chase, having subtle references within the story, such as using Elesis as a new character in the game.
