A super rare, sealed Atari 2600 game called Music Machine sold on ebay for $5,250.
The game was sold in Christian stores and there was an LP and cassette with the same name. The game tries to teach kids about the "Fruits of the Spirit", which are love, joy, patience, kindness, goodness, faithfulness, gentleness, self-control.
Here is how the seller described it:
"Symbols representing character-building qualities (the Fruit of the Spirit) are raining down from above. Stevie and Nancy need your help to collect the symbols and to avoid the mischievous pudgeons...and with each gift of Love you collect, the symbols rain heavier and faster. Get points by collecting the Fruit of the Spirit symbols. Play alone or challenge a friend. Read the booklet and learn a valuable lesson."
Apparently Christian video games make great collector's items. Other games like Super Noah's Ark 3D, Joshua and the Battle of Jericho, and Sunday Funday are all rare and fairly expensive too.
Maybe I should take a trip down to the local Christian bookstore and buy every video game they have in stock. Or maybe they no longer make Bible video games because they didn't sell very well and that is why they are so rare and expensive now.
On a side note I can still sing some of the songs from the Music Machine cassette that I made my mom play in the car when I was a kid. If only I had begged her to get the video game too!
