I have played a couple or so of private servers and I must say that OriginsRO is by far the best of all of them. This is Ragnarok in its original state. No cash shop, no imbalance items, just chilling and going around the whole world of adventure. I really hope that the GMs can incorporate new world from renewal and adapt it to classic server :)

Perhaps one of the private renewal servers which is up to date. However, I felt like it is too much pay2win. If you are thinking of getting to the events in the game, probably need to spend around $500 in order to make your character updated and strong and useful in top parties. As soon as you start to make your character, things go fast - you pretty much reach the end-game in like a day or so which ruins the real spirit of Ragnarok. On the side note, GMs are quite active and helpful.
