Solved Answer

Lost Ark is a fantasy multiplayer online action role-playing game that became the second most played game on Steam within twenty-four hours of release. Many users find the game enjoyable and praise the graphics and world design. The story creates an immersive experience, and the character customization abilities are said to be impressive.
