This is the first MMORPG that I discovered by chance and played when it was still Pay to Play. The highest character classes during those times were the Priest, Knight, Wizard, Merchant, and Hunter classes. I took a long break from playing due to my studies at school.
This is based on Norse mythology and on the manhwa title "Ragnarok" by Lee Myun-Jin. Sadly, the manhwa was left unfinished but the game goes on.
Character designs are 2D but in a sort of 3D environment.
The game itself will run even on a "normal" or non-gaming GPU.
OST is great to hear.
The quest stories are great if you read those dialogs.
As with other online games, there are bots that farms for items but the game masters are doing whatever they can to reduce the impact on legitimate players leveling up their characters. There is no in-game advertising from other companies except by those bots that sells in-game currency in exchange for real money (scam). That practice is illegal though and if a player is found to be involved in that transaction. Then, character ban will result and sometimes character and items deletion.
Just don't do something illegal in-game and this will be a good game. Lots of grinding if you go solo. So join a party and do quests to avoid too much grinding.
