Lately, we've all witnessed a staggering increase in the number of Lineage II trial accounts that are being abused. As we all know, the purpose of a trial account is to give someone who hasn't tried Lineage II before a chance to give it a test drive. Unfortunately, our trial codes are being used more and more, by individuals who are not true members of our community, in ways that harm the player experience. We have received an overwhelming number of requests from our player community to put a stop to this trial account abuse; so, we have made a reluctant, but absolutely necessary decision. As of today, April 29, 2008, we will greatly limiting trial account creation. Current trial accounts that have already been activated will be left active.

We will also be making some changes to how trial accounts can be acquired. For the time being, trial codes acquisition will be limited, but you will still be able to acquire trial codes via the Refer a Friend program. We will be monitoring all trial codes very closely. This is something that we believe will actually create a better atmosphere for our players in Lineage II and, especially since our community has requested this move, we are happy to oblige.

For those former and potential players who may in the future wish to use a trial code with the intent to simply try out Lineage II, though limited, trial codes are still accessible! You can get a trial code from an existing player via the Refer a Friend program. The Lineage II team will be monitoring this situation closely and will update our community on further developments and policy changes.
