World Class Baseball is a baseball simulation game released for the NEC PC-FX. The game likely allows players to manage and play as a baseball team, engaging in simulated matches against computer-controlled opponents or other players.  Features such as player customization, team management, and realistic baseball mechanics would require further research to determine. Its release in the USA suggests that, unlike many PC-FX titles, it had a wider release than just in Japan.
