Contrary to the title, this game has nothing to do with bass guitar playing. Bass Master 2000 is a Nintendo 64 exclusive fishing simulation. The game does it's best to accurately portray fishing, except with magical underwater angles and famous fisherman Shaw Grigsby giving commentary in your ear. You'll fish on real lakes, catch real fish, in realistic areas of the lake depending on the time and weather. The controls are intuitive and the settings force you to learn the essentials of fishing.
There is, unfortunately, no Fish vs Fish capture the flag mode of any sort.
