"When we came up with the concept of a "box art" for Mega Man 9, we thought it was kinda funny, since there would be no real retail box for a dowloadable title. The premise of our marketing concept for the game was to promote this title like it was 1987, complete with cheesy art and game descriptions (read the back of the box) that had little to do with the actual game.
We then started to think, well why not? Why don't we recreate an old NES package complete with a real NES cartridge? So, here it is. What do you think?"
