The original Ragnarok Online was one of the very first Korean MMORPGs to enjoy popularity on an international level, and Gravity followed it up by releasing an open beta for Ragnarok Online 2 in 2007. Unfortunately, feedback gleaned from the open beta was largely negative, and so, Gravity went back to the drawing board.
Eventually, Gravity announced a completely new version of Ragnarok Online 2, built using a new engine (Gamebryo) and with new systems and features. The remake was titled: Ragnarok Online 2: Legend of the Second.
This week, Gravity have announced that after several months of testing, Ragnarok Online 2: Legend of the Second is finally going into open beta in South Korea, starting on February 22nd.
