Sports Talk Baseball is a first-party baseball sim for the Sega Genesis that was supported by the MLBPA license, allowing the game to use the names of players from the major MLB teams - it did not, however, have the MLB license and so team names simply referred to their cities of origin. It originally began as Pro Yakyuu Super League '91 in Japanese markets, which would later be followed by Pro Yakyuu Super League CD for the Mega-CD system.
The game is credited for being one of the earliest baseball games to have a play-by-play announcer narrating the game in progress, using the same commentary tech that Sega had premiered in their football sequel Joe Montana II: Sports Talk Football released a few months prior. STB also fully rated every player in several skill categories, as well as including battery-powered memory for season W-L tracking: players have to complete three games before the game would save their progress, however. While several wonky features did make it into the game (the speech lagged terribly behind play, AI base-running and attempting to throw runners out had lots of quirks, 10-run slaughter rule), STB was well-regarded for its time. The Japanese version of the game lacked the commentary track, but instead had a few scattered sound samples as well as ouendan music (i.e. a cheering squad, who would play music during the game with taiko drums and horns).
Trivia: The winning team always had a picture of the game MVP in the post-game scoreboard. It was always the same player for each winning team, no matter if that person played or how they performed.
