The game seems to manage lag decently and it never became an issue even in crowded locations. Players can form in to hunting parties to share experience and monitor one another's hit points. You can also form Blood Pledge's which are similar to the guilds of other games. You can even upload your own emblem to be displayed in game. You can even besiege a warring Pledge's castle.
Sieges are one of the most interesting aspects of the game.
You can find a well written article on sieges in Lineage by clicking here . Killing a member of a Blood Pledge that you are at war with will not lower your alignment. Killing another player who you are not at war with will lower your alignment. There is also a No-PK server for those who do not want to participate in PVP at all. Another feature I really like is the darkness.
