Great Baseball

Great Baseball is a baseball simulation developed and published by Sega for the Master System in 1985 as part of the company's "Great" line of sports titles. The game adheres to standard baseball rules, with nine innings and the ability to select from six generic teams designated only by initials (C, D, G, T, W, and S), with no player names or statistics. Multiple modes are available, including one and two-player standard games with either automatic or manual fielding, and a Home Run Contest where players get 20 pitches to hit as many home runs as possible. When pitching, players can curve the ball left or right, speed it up, or slow it down. Batters can position themselves and execute bunts or full swings, and baserunners can be instructed to lead off or steal bases. The game uses a high view of the diamond that switches to a wider outfield view when the ball is in play.

Master System

This version was first released in Japan on December 15, 1985, on the Sega Card format, and was also released in Taiwan. It was never officially released in North America or Europe; instead, Sega developed a completely different, significantly upgraded version for Western markets in 1987. The original 1985 Japanese release received mixed reviews. While some critics praised its sound, graphics, and animations as high quality, the game was criticized for the inherently stop-start nature of baseball making it poorly suited to a video game, preventing full immersion. This original Great Baseball should not be confused with its 1987 Western counterpart, which is a separate title with enhanced features.
