Thought on Ragnarok Online 3?
So after seeing gameplay clips and such, it looks like a modernized version of RO 1 and not a remake with modern graphics. The way the world is shaped stayed almost the same. They did really well with the graphics. But the gameplay and progression is different.
From everything shown so far, the gameplay loop is completely different. Instead of spending hours pulling mob trains across maps to level up, you hit max level pretty fast just speeding through the main questline. After that, it turns into a Lost Ark style loop. You queue up for instanced dungeons with a party to grind for your end-game gear. The focus has completely shifted from open-world mob farming to daily missions, time-gated events, and instance dungeons.
Cards are now easier to get, instead of grinding 1000's of mobs to get a card, you now can get them from card packs ( yugioh style ). But you can also get them from Instance Dungeons, Daily Missions & Events, Card Crafting. However you need duplicate copies to level them up.
Classes wise, it got all the classical jobs from the original RO and their evolutions. Swordman, Thief, Mage, Acolyte, Archer, Merchant. But it does not have the Ninja and Gungslinger. All the jobs artwork can be visualized on the official RO3 website.
