Jan Sangoku Musou

Dynasty Warriors Mahjong (雀・三國無双, Jan Sangoku Musou) takes a different approach to a popular eastern pass time, Mahjong, in this title. There are no battlefields involved but there is interaction between warring generals with dialog that somewhat parodies Dynasty Warriors 5. This title is only available in Japan. Koei has no current intentions to release this in North America or in Europe.

Players name their own "Mahjong warrior" from 32 preset designs and 6 different voice sets. Once the player has decided on a character, they can choose to either participate in a tournament or in one of the game's story modes. Each match in story mode has four participants, the player being set against three characters from the Dynasty Warriors series.

The rules are similar to other Mahjong games but includes cuts of the series' characters during matches. Image displays are often voiced and essentially give hints regarding the opposition's situation. These cuts sometimes include the characters posing with their weapons or displaying emotions rarely seen in the series, which makes these instances unintentionally hilarious.

Gameplay
The rules and scores are very similar to form of Japanese mahjong, particularly the type that is found in competitive mahjong games and yaku. Players can still forfeit their hand and use pon, chii, riichi, or kan. Though the player is allowed to change certain rules, there are rules the remain by default.
 * Tiles consist the tiger, character, bamboo, and honor tiles. Flower and joker tiles cannot be used.
 * The starting amount is usually set at 30,000. On certain stages, it can also be 16,000 or 20,000 points.
 * All games are competitive; there is no option for solitaire Mahjong.
 * The Kokushi Musou move (国士無双) and the Seven Pairs move can be done no matter what the game setting.
 * Only the abortive draw, Kyūshu yaochūhai touhai, can be made.
 * Unless it's free mode, the player can clear a stage by succeeding in certain goals. A couple objectives include reaching a high rating for specific winning hands or remaining at a certain amount of points by the match's end. They do not necessarily need to have the highest score or have another character at zero points.
 * All hands are considered closed; an open riichi cannot be performed.

Mahjong Toupai
The story mode. There is a scenario for each kingdom and a "dream" story mode that is unlocked once the player beats all the other stories. Players travel from six different locations for each kingdom.
 * Wei
 * Cao Cao, bored and restless, calls for the greatest mahjong warriors in the land to satisfy him with a game. Xiahou Dun asks the player to help him out by finding two other players. During this time, Wei is at war with Yuan Shao but that doesn't stop Xiahou Yuan from calling him over for a game.


 * Wu
 * A grand banquet is being held for a mahjong tournament. The player is asked by Sun Jian to help with the preparations while he's away to escort his daughter on a faraway trip.


 * Shu

 * Musou
 * Final and longest scenario that pits the player against three opponents from each kingdom. They challenge the player to prove who is the better mahjong warrior of the era. A brief summary for each team's dialogue is attached.

 * Da Qiao, Sun Ce, Guan Ping - Da Qiao cheers on her husband and he gets embarrassed. They share a tender moment together while Guan Ping watches on being a bit jealous. He wants to win the match to someday share the same type of happiness.
 * Zhou Yu, Xiao Qiao, Cao Ren - Zhou Yu promises to play Xiao Qiao her favorite song if they win. Cao Ren scorns their open display of affection on the battlefield. After the player wins, he bashfully says that he'll act the same after the wars are over.
 * Zhao Yun, Zhang He, Diao Chan - the good-looking "cho" team; Zhang He gathered them together since the Japanese pronunciation of their names are a "beautiful" pun of the word butterfly.
 * Xu Zhu, Meng Huo, Dong Zhuo - rambunctious giants; Meng Huo and Dong Zhou fight over treasure while Xu Zhu tries to calm them down with a Mahjong match.
 * Sun Shang Xiang, Xing Cai, Zhang Fei - Sun Shang Xiang and Xing Cai talk about pleasing their fathers but the latter can't find herself to cheer for her parent. Zhang Fei joins the team to show her how cool he can be.
