World Series Baseball 2K3 is a follow-up to World Series Baseball 2K2. This installment of the series includes several new features:
The new ESPN broadcast license allows improved replay and cutscenes, adding further realism to the presentation of baseball
Hall of Fame legends join the complete list of MLB teams, players and coaches, along with retro and alternate uniforms for all teams.
Some of the classic ballparks from yesteryear are fully featured, including Crosley Field and Griffth Stadium.
Other additions and enhancements include improved animations for players, a new jump button for outfield catches, a full list of MLB awards to win during the regular season and playoffs, and updated team lists including the latest rookies and trades made during the offseason.
GameCube and Windows versions were in development, but eventually cancelled. The Xbox version was the core version. The PS2 version was developed at a later stage and ran into trouble because a lot of the content was tuned especially for the Xbox version and never ran on the RenderWare engine on the PS2 before. The developers took a different approach and dropped everything to try and write new technology for the PS2 version. As the game was late, there was a lot of pressure from publisher SEGA and the shipped PS2 version did not run as well as the Xbox version.
