The Nintendo 64 was a classic console, everyone had one. They sold over 32 million so there’s bound to be some people still playing it.
Out of the total 387 games released, 83 were for the Japanese market, so this collection represents about 75% of the western N64 catalogue. Of those, 121 are factory sealed games, 96 are complete games, and 16 are just cartridges. There’s bound to be a few rare games in there too.
