As general manager of a Major League franchise, it is your job to set ticket prices, concession prices and manage a team of players. You are put in charge of signings, negotiations and basically trying to build a team that can go all the way to the series. Between games, you can access a player's screen that gives you an idea of what is going on around the league. You can check on the status of certain players, see who the up-and-comers are and basically just try to keep up with the Steinbrenners.
Although a majority of the game takes place in the back office, you can also make in-game decisions like deciding the batting order, pitching rotation and implementing a team strategy for each of your opponents. You don't have to sit through every game if you don't want to. The number of simulation options is flexible and lets you go through a single week, month or even the entire season.
Nearly every player in the league is featured in the game, although there are a few noticeable roster errors that might annoy more ardent fans. A number of minor league players are also available. In addition to playing as current teams, you can also choose to replay past seasons going all the way back to the early 1900's. Better yet, the game adjusts the economic model to fit the era. Speaking of prices, you can also set a league-wide cap, placing teams on even ground.
For the more creative types, you can also create your own teams and stadiums.
