I don't know if you already have a license to use Ragnarok and Zeny as currency, what I do know is Gravity is the original Ragnarok game developer who has Zeny as the in-game currency. I'm just asking a very simple thing so that when your game is famous and developing, you don't clash with gravity as the original developer.
Hi. First of, the name of the game is BNB Ragnarok. The game is inspired from them, inspired. Also Ragnarok is from Norse mythology and basically a term for tragic future events. The game have different concept of heroes/monsters and the gameplay is different. I don`t see any trademark for zeny as well. The game is inspired by the term Ragnarok and it is not a copy.
Inspired eh, yet you blatantly use an image of Geffen town from Ragnarok online on your promotional video on Youtube (also embedded on your website).

Unless you can provide actual sample gameplay that would look entirely different from the numerous Ragnarok online games, I'd say you're just using the game's popularity for a quick cash grab.
