The object of the game is to cultivate a farm to prevent the land from being used to build an amusement park.

As with the previous game, the player may choose to play as a boy or a girl.

The initial goal is that in three years time, the player must bring up the farm by growing and selling crops, and raising livestock.

If he thinks it's looking good, the player may continue the game for another couple years.

Crops are a primary source of income in Harvest Moon 2 GBC.

They become agitated and stop producing milk for three days if the farmer is unable to feed them (due to the farmer getting a cold or a storm/bad weather); if the player feeds them and brushes them, after 3 days they should restart milk production.

Similar to cows, feeding them for 3 days straight should make them lay eggs again.

When sheep have a higher happiness rating, they produce large pieces of wool, which sell for 250G apiece.

The species of fish and insects that the player caught would be displayed in the picture books located in the library in town.

The fish and insects that the player caught (as well as flowers that the player grew) could also be traded by Game Link Cable to other copies of Harvest Moon 2 GBC or to the game Legend of the River King 2.
