All-Star Baseball 2004

All-Star Baseball 2004 for the Game Boy Advance is a licensed MLB title featuring all teams, stadiums, and a roster of over 800 players. Gameplay involves a distinct batting interface where a large, rotatable triangle indicator is used to aim and direct hits, with a comparable system employed for pitching. Defensive fielding allows for manual base selection or can be delegated to automatic CPU control.

The game supports both single-player and multiplayer via link cable, with several modes including Exhibition, Season, Playoffs, and a Home Run Derby, though it omits a Franchise mode. Player progress, trades, roster changes, and a collection of 250 unlockable trading cards are saved through a battery backup. Compared to its 2003 predecessor, this version introduces more sophisticated AI, such as CPU pitchers capable of throwing balls outside the strike zone, and faster base runners who can attempt extra-base hits.

Enhancements extend to presentation, with additional animations for pitcher follow-throughs and batter walk-ups. Visual details like celebratory scoreboards and stadium-specific elements such as flags are present, while new play-by-play commentary is featured in the audio.
