The Blue Marlin (ザ‧ブルーマリーン) is a 1991 fishing video game developed and published by HOT・B for the Nintendo Entertainment System (NES). Following in the tradition of its predecessors, The Black Bass for MSX and The Black Bass for NES, the objective is to win a tournament by catching the largest fish in the time allotted. The Blue Marlin features four tournament rounds (one in Florida and the other three in Hawaii).
The player controls a fisherman who is competing in a tournament. The objective in each round of the tournament is to catch the largest billfish. These fish include blue marlin, black marlin, striped marlin, swordfish, and sailfish. Other fish that can be caught include dorado, barracuda, tuna, and sharks.
As the player fights fish, there may be several events that occur that the player must respond to, such as a smoking reel or a marlin attempting to tangle the line in the propeller. Other events are static, such as the fish biting off the line or the fish becoming exhausted. Each of these events changes the dynamics of the fight, such as changing how much line the fish has or how tired the fish is.
There are three attributes that the player can increase as they fight more and more fish. These are Muscle Power (ability to pull in heavier fish), Body Strength (ability to fight a fish longer), and Skill (ability to respond to events properly).
The Blue Marlin features a password system to save the player's progress. A password is generated at the end of every tournament round, and after the tournament is completed (with the player victorious). If the player uses this password to begin a new tournament, they can start over with all of their attributes from their previous game.
