For those that have always been interested in checking out Ragnarok Online (RO) but didn’t want to pay a monthly fee, you can play on one of the private servers at http://www.apocalypse-ro.com/. They accept donations and offer game items for donating. I would highly encourage doing this if you get into the game.
While the private server is a bit different then the main stream version, you can still find out all you need to know on their forums. It’s completely free to sign up and play. Just create an account and then you’ll have access to their forums/guides. Hope to see you around!
