You might not know this if you grew up in the later eras of Nintendo, but the company ran an esports competition called the Nintendo World Championships way back in 1990. The event toured 29 American cities and players from across the country gathered to compete using a custom Nintendo Entertainment System Game Pak. The cartridge used in the event went on to become a prized collectors’ item, but now, players will get a chance to buy a physical item directly inspired by it.
