Nintendo PowerFest 94 [Super Nintendo] – Price: $23,100

Nintendo held a fourth video game competition in 1994 called “PowerFest 94″. For this event they produced roughly 30 special Super Nintendo cartridges containing Super Mario: Lost Levels, Super Mario Kart, and Ken Griffey Jr Baseball. Again, each player had 6 minutes to get a high score and the top scores were invited to San Diego for the finals.

There are only two of these cartridges known to exist today. But both have a different scoring system (one from the finals and the other from the preliminaries).
