What it means is that you need to consider their liking and preferences to games. The people there really prefer p2w ( pay to win) games. meaning they really want to spend money and a lot of content to be only for RoI Gold  who pay. As far as a localization ( and our is the case) I really think Nexon are in a few ways restricted by the devs from the far end on what they can and cannot take money for or make free. Making a localization is basicaly like a rent. You can get money from it, but yet again you have to pay a solid part of the income to the devs of the game, and obey their wishes. But that's going a bit off topic.
