This is the game you have been looking for. From Bosten to San Diego and back to New York. It is all here.
In career mode you get to create a player and start a new career. Have him go throw Spring Traning then the minors. You get traning hours depending how good you play. Once you get good you could ask the maneger to call you up.
Become a All Star, make it to the Wolrd Series, Win MVP. Even become a Hall a
Famer.
Of course, the game includes all 30 Major League Baseball teams and stadiums, thousands of actual players, and a decent assortment of alternate jerseys and spring-training ballparks. Two all-star teams are available, as are two legends teams, although those need to be unlocked by winning games in the various play modes. Triple-A and double-A clubs are also available in the career and franchise modes, but the only real players included in them are those who have already had previous major league experience.
