Great Baseball
棒球：Great
Great Baseball is a baseball simulation released by SEGA in 1985 for the Sega Master System. Players take turns batting and pitching in this two-player sports title. The game features simplified controls mapped to the console's single-button interface—players swing by pressing the action button with proper timing to make contact with pitches. Gameplay progresses through innings with basic statistics tracking hits, runs, and outs. The pitcher controls pitch placement and speed, while the batter aims to hit balls into fair territory. Great Baseball captures the fundamental mechanics of baseball in arcade form, offering competitive matches between two human players. The straightforward presentation and accessible mechanics made it an appealing title for Sega's early sports library.
