It's really a remake of RO. Thief for example have a ASPD buff, Acolytes passives are mixed in one, Merchants having a passive to drop zeny from monsters, Hammer Fall dealing damage, everyone being allowed to vending and that's only the beginning. It's truly a overwhelmingly good and fresh sensation of discover. Playing RO since 2004 and countless privates, this one here is one of the best. It deserves a shot, even if just to see the differences. I hope it lasts long years.
