There will be six classes, with some determined by gender. Nation battles plan to support 1,000 players on each of the two sides in massive siege combat. Aside from River Pap, there are quests, a crafting system, and more. Eventually, the possibility comes to rise what are being called "Daughters". The Daughter system is a pet mechanic where the pets come in the form of little girls. Like your player characters, these Daughters will grow up with training, and each one promises to be unique depending on various factors, including how close you are with her. RO Zeny players will converse with you and this, among other outcomes, will impact the effects your pet will bestow upon you. The Daughter will also learn new skills as she grows that can aid you in battle.
