Lineage II is a Massively Multiplayer Online Role Playing game with a fantasy setting. It has fully 3D game play, with the ability to play several class types. One of the biggest features is the ability to form clans and siege castles.
The game is actually set as a prequel to the world available in Lineage and takes place in the three kingdoms of Aden, Elmore and Gracia. You can currently choose from one of five races: Human, Orc, Elf, Dark Elf and Dwarf. The game play is both quest and item driven.
Lineage II boasts a, "Synchronized Tactical Combat System," which implies that combat is real-time rather than turn based allowing for greater diversity in player-tactics. Another big feature is the taming system, that allows you to tame creatures, ranging from dogs to less likely ones such as dragons.
