Matthew Kim, also known by his stage name Big Matthew in the K-pop group KARD, revealed that video games serve as a crucial link to his family. Kim relocated to Korea to pursue his entertainment career, but gaming has become a way to maintain his familial bonds.

His initial exposure to gaming came from his father, whom Kim described as a formidable player of Super Mario. This early introduction has evolved into a continued passion, with Kim currently playing Call of Duty: Warzone alongside his younger brother. The shared activity provides a consistent point of connection despite their geographical separation.
