.hack// sees an interesting entry into our Anniversary posts. An extensive 4 part story over 4 games included with short anime episodes to go along with the story were released in quick succession one after the other.
.hack//Infection was released on June 20th 2002.
.hack//Mutation was released on September 9th 2002.
.hack//Outbreak was released on December 12th 2002.
.hack//Quarantine was released on April 10th 2003. Technically not up for its 15th anniversary yet, but its close, and felt missing from this post.
