Kyuukai Douchuuki

Kyūkai Dōchūki (球界道中記, Baseball World Traveler's Journal) is a arcade game that was released by Namco in 1990, only in Japan. It runs on Namco System 2 hardware, was the company's first (non-polygonal) game of the 1990s, and features characters from their first 16-bit arcade game of Yōkai Dōchūki (known as Shadow Land in the United States), which was released three years earlier; as with that pioneer NS1 game, it used a Yamaha YM-2151 FM sound chip for its songs, but it used a C140 custom sound chip for its sound effects and speech sampling (as opposed to a PSG and DAC).

The gameplay is similar to that of Namco's own series, (which was only comprised of two titles at the time this game was released - so it did not constitute a series back then), except that the players have a total of thirty-six different teams to choose from in the Japanese (the teams in this league are also identical to those from that World Stadium game series), Arabic, German, Humbaba, American, Russian, and Chinese leagues. There is also a total of seven different playing stadiums to choose from (one for each league), and the game was later converted for the Sega Genesis in 1991.

This game also features a cameo appearance from Valkyrie (as in no Densetsu, which was released in the previous year and also ran on Namco's System 2 hardware), and Namco's signature character Pac-Man can also be seen on some television screens in his anthropomorphic form wearing a purple bow tie; some members of the seven different stadium audiences are also wearing masks (that make them look like other Namco characters), and they cheer when the Katakana text "Hōmu ran!" (literally "Home run!") comes up on the screen and the current score appears below it to show who is winning.
