Unfortunately for LOTRO players in Japan it seems that today marks their last day in Middle-Earth on a native server. I’m unsure on whether or not they could play on European or US servers, however, my guess is they could with an additional purchase and possibly some considerable lag. It seems that those who purchased the game may be eligible for a refund (I’m not proficient with Japanese, and Google Translate can only do so much), but it may be worth contacting Pureichiketto here for a refund. Players can also contact firstname.lastname@example.org for more information
I’m sad to see this happen, but unfortunately Eastern and Western MMO’s do not always translate well into different cultures. Hopefully some of the players will make their way onto different servers and still enjoy the game!
