Sega Network Taisen Mahjong MJ2 (2004)

Release Date: March 6, 2004
Developer: Sega

The sequel to Sega Yonin Uchi Mahjong MJ, and the second overall entry in Sega's MJ series of Riichi Mahjong arcade games. This game had a higher focus on online play than its predecessor, introducing the League Battle mode. In addition to the buttons, a touch screen was also added for ease of operation, something the original game lacked.
