"iRO2 wasn’t suppose to be released on May 2013 and the reason it got released early was because the China partner during that time was evaluating the game. One of the reasons iRO got colo before the Culvert Abyss update.
Unfortunately for Gravity Co., the China partner wasn’t too impressed with the game performance and the content and as announced on November 2013, the license agreement was terminated. As a result of this, Gravity loses $20 million.
And…as a result of that..we got AoV earlier than expected and that update pretty much destroyed the game.
And…..as a result of AoV wrecking the game, on April 2014, the Phillipines partner terminated the license agreement for RO2. Gravity loses another $3 million.
And………….as a result of this, the jump event was implemented in hopes of getting PH players to play on iRO2. This was purely a WP decision, not Gravity Co. Oh yeah..this also resulted into unwanted zeny sellers. Note that Gravity Interactive “allowed” the spammers to exist."
