In July 2010 it was announced the first iteration of the game had been scrapped, and a new version, Ragnarok Online 2: Legend of the Second, would be developed in its stead. The new iteration of Ragnarok Online 2 returns to the systems and mechanics of the original Ragnarok Online while keeping the 3D engine. The game engine was changed several times since its predecessor opened its long running closed beta in 2007. It was mentioned that the new version of Ragnarok Online 2 will be using the Gamebryo engine. The previous iteration used Unreal Engine 2.5.
In addition to the job system, there is also a newly introduced Dual-Life System in which characters can take upon a secondary role. These roles offer unique abilities that help in expanding the capabilities of a specific character.
Of all the classes brought back to life from the original Ragnarok Online, only the Merchant class was not included. The new Dual-Life System allows character development in a whole new light. Instead of using a Merchant to set up shops and vend, players are enabled, with a new function, to set up their characters as NPC's (non-playable characters) while they are offline, rendering their services (healing, crafting, tailoring etc.) to active players to make a profit.
In a recent interview with GRAVITY Co., Ltd. CTO Jin-soo Jun, it was revealed that the card system will indeed be making a comeback, but this time the cards will be attached to the character instead of individual items. The reason for this change is the fact that in Ragnarok Online many rare items were often overshadowed by low level items socketed with powerful cards. This made the inherent abilities in rare items a lot less relevant, and it proved to be a limiting factor when making new content. Furthermore, in Ragnarok Online, many players had trouble obtaining these cards because they were too rare. To counter this issue GRAVITY Co., Ltd. implemented cards in ranks of bronze, silver, and gold. Therefore a gold card will be difficult to obtain, whereas the bronze card will be relatively common. This new system had then been modified in the "Limited Edition Test" so that instead of bronze, silver, and gold cards, there will be regular and special cards. By combining 5 of the same card, players will be rewarded with a special version of that card which will further increase its stats. Once a player has the maximum amount of cards equipped, you must destroy one of the equipped cards to replace it with a new one. Replacing a special card with a new one will result in the card not being destroyed, but sent back to your inventory instead.
The pet system from Ragnarok Online will also be making a comeback. Players will be able to tame monsters which will provide characters with special abilities and with intimacy have cute performances. At this time there are no plans to have pets directly assist in combat.
