The story mode focuses on raising players. If you select a male character as your in-game counterpart, you're given a female counterpart, and vice versa. You must raise your character and your partner. Characters that you've created and raised can be transferred to the Game Cube Mario Golf Toadstool Tour and be used for play in that version.

Connecting the two versions of the game together will also result in some new courses opening up in the GBA version. You'll also be able to apparently transfer spectator comments between he GBA to the GCN.

Incidentally, the included Wireless Adapter is also required for opening up new features. When using the wireless adapter, the game will give you access to 16 clubs on top of the seven that you start off with. The game will also, apparently, include a way of making clubs.
