The game features all 12 Nippon Professional Baseball teams, and both the Pacific League and Central League All-Star teams (circa 2006, but with changes made for traded and/or retired players). The difficulty level for the game is adjustable. The easiest mode will appeal to younger players who have probably never played a baseball game before in their lives, and the hardest mode—known as Spirits Mode—will give even the most experienced and advanced players a challenge with superior AI. Other modes can be selected in a sort of pseudo-gameplay sliders mode. For instance, gameplay speed can be increased, as well as pitch speed (which can be set to "real" speed). The basic batting interface is a silhouette of a bat which influences how the ball will travel. Depending on when and where contact was made, that influences where the ball goes. The pitching is a 2-click system where the player selects his pitch around a grid, presses X to start his delivery, then pressing X as one circle converges on another to try and perfectly time the pitch.
