THIS IS TENGEN BLACK CARTRIDGE VERSION FOR NINTENDO NES SYSTEM.
Though RBI did not have an MLB license (giving them the right to use team nicknames or logos), they still gave you the selection of 8 MLB teams listed by city name - Boston, California, Detroit, Houston, Minnesota, New York, St. Louis, and San Francisco. There were also two All-Star teams, American League and National League, featuring players from teams other than the eight represented in the game. The eight teams were chosen because they were the playoff teams from the 1986 (Boston, California, Houston, New York) and 1987 (Detroit, Minnesota, St. Louis, San Francisco) MLB seasons. The All-Star teams featured such established veterans as George Brett, Dale Murphy and Andre Dawson, none of whom appeared on any of the other teams in the game, as well as up-and-coming players like Mark McGwire, Andres Galarraga and José Canseco.
Each player has different capabilities in the game; hitters vary in ability to make solid contact, to hit the ball with power, and their base running speed. Vince Coleman is the fastest player in the game; it is very difficult to catch him stealing second base. Pitchers vary in pitching speed, and the amount by which you can steer the ball left and right during its flight. Pitchers also have varying stamina; as a pitcher gets tired, the ball slows down and is harder to steer. There is no evidence that fielding abilities correspond to individual players.
The abilities of each player do not necessary correspond with the statistics shown on the screen when the player comes to bat or takes the mound. These statistics are generally accurate, with many exceptions (see below). They do not change during the course of the game or sequence of games.
