Which feature of the Game Boy inspired Satoshi Tajiri’s idea for Pokémon trading?

The Game Boy’s Game Link Cable inspired Satoshi Tajiri’s idea for Pokémon trading.

The cable allowed two Game Boy systems to communicate, originally supporting multiplayer interaction such as competitive play. Tajiri imagined using that connection to transfer collectible creatures between players rather than merely having them compete.

This idea also connected with Tajiri’s childhood interest in collecting insects. The Pokémon concept combined discovery, collection, and exchange into a portable role-playing game. It gave players a reason to own different versions and meet other players, since certain creatures were unavailable in each version.

The Game Link Cable is sometimes confused with later wireless functions or with the Super Game Boy accessory. Wireless trading became important in later generations, but the original design inspiration was the physical cable connection between two Game Boys.
