Yea even without advertisement this game lives off word of mouth even now in mmorpg forums people still occasionally bring up this game and of course on thoseserversthatcantbenamed plenty of people aware of IRO.
Remaster could be interesting but they seemed to give up on PC maybe the next interesting thing could be a official ragnarok VRMMO.
full 3d update... like the cellphone RO it's than even possible? i mean change the skin of the game or idon't know, i believe is the dream of all players
