There rare, and then there’s RARE. The NES’ Nintendo World Championship game is considered one of the most sought after possessions of a video game collector. So how much does one of the rarest video games ever go for? You’d be surprised. An auction has just ended for an NES cart of Nintendo World Championship, and it sold for a mind-blowing $99,902. The auction began at $4,999 and quickly accelerated toward the six-figure mark during the final two hours of auction.
