Obviously this is iRO & you're right kRO doesn't OWN the game. kRO doesn't own kRO just like iRO doesn't own iRO. They are both servers. The only provide us with certain things like I've been talking about as far as gear. Gravity owns the game.
Gravity Co,. LTD. is located in South Korea, and they own rights to Ragnarok Online. And kRo is their main server so if anything, iRo doesn't own the game either. So everytime they want to do something major, they need confirmation from its HQ, which is mostly kRo dev team. Gravity owns the game yes, but They have seperated dev team for kRo server, so whenever CM or people are referring to Dev team, its usually about kRo Dev team. so we could say Gravity is kRo. Just like someone said, iRo is just running the server, but kRo dev team not only running the server, comes up with idea, check with Gravity, and release them.
