Tecmo Cup Football Game
type : unreleased new game
(from wikipedia) After releasing a Captain Tsubasa video game adaption for the NES in 1992, a follow up version was in development for the Genesis the following year. This version was planned for release in European regions, and would have stripped the Captain Tsubasa (largely only known in Japan) references, but retained the game core gameplay of mixing association football with turn based interactions often part of JRPGs. The game was far enough along to be reviewed in multiple video game magazines in 1993, but the game never released for the Genesis. A late build of the game leaked onto the internet years later, while a similar game released for the Sega CD in 1994.
