Lineage
Lineage was released in 1998 and still represents one of the most successful MMORPGs in Asia today. This is due to the underlying gameplay principle. In Lineage, you first create a hero from five classes, with whom you explore a vast world from an isometric perspective.
What you do in this world is up to you. You can join forces with other players to hunt the numerous monsters to become better over time. Those who achieve the status of a noble have the opportunity to make a blood oath. These oaths connect players with one another. Groups can then fight each other.
It is even possible to take castles, whereby the victor can set taxes for the adjacent buildings. This creates a constant war among players, which keeps Lineage interesting even today.
