I just recently picked up an unreleased NES game, so that probably has to jump into my top 5.  It is Mike Ditka Big Play Football, I also won the cover art for the unreleased box on ebay the same week

That is awesome. How does the game play??

[NationalGameDepot]

It is pretty much a ported over famicom game, Quarterback Scramble.  It has different screens and text and is of course in English.  The game is kinda bad at first glance but it grows on you as you play it.  Plus the cool factor of having a game that was never was released makes it even better to me.

Since I have the artwork for it as well,  I plan to have the game released and sold at CGE next year in Vegas.  It will have a box and manuals made as well, should be fun.

Such an awesome find! Did you also find the cart on ebay?

[NationalGameDepot]

the art was from ebay and the cart was from a private sell outside ebay from a  member on NA.
