Nintendo World Championships is regarded as one of the most expensive NES titles available, but did you know it had a sequel?
Known as Nintendo PowerFest 1994 to many and Nintendo World Championships II to some, this sequel is rarer than its predecessor with only two known copies available. A writer of Price Charting blog managed to grab himself a copy of the rare title for a whopping $12,000!
You can read about how he came to obtain this title on his blog post, let’s just say that it sounds like a nuisance that isn’t worth it in the end.
