Short answers, pulled from the story.
Lineage W is a massively multiplayer online role-playing game developed and published by NCSoft. It is the fifth major installment in the Lineage series, combining elements from the original Lineage game and Lineage II.
Lineage W was released on the 4th of November 2021 for Android, iOS, and Microsoft Windows in East Asia. It supports cross-platform play across mobile, PC, and consoles, with PlayStation 5 and Nintendo Switch releases also planned.
Lineage W earned an estimated 16 billion won per day during its first four days of release in South Korea, setting a record for the highest first-day revenue of any NCSoft game. By December 2021, estimated sales exceeded 200 billion won, approximately 166 million dollars.
Lineage W was initially planned for a worldwide 2021 launch but remained unavailable outside Asia. Poor sales performance in Japan, Singapore, and the United Arab Emirates is cited as a likely factor behind NCSoft's hesitation to release the game in Europe and North America.
Lineage W uses an NCSoft in-house AI-Translation system that translates chat, community messages, and communication in real time. The game also includes voice-to-text input to further ease communication between players of different languages.
NCSoft CCO Taek Jin Kim described Lineage W as "the final Lineage" before the game's release. He made this statement during the period surrounding NCSoft's THE WORLD showcase events, when the company also announced it would be the largest launching title in the company's history.
