Simplynes - Dedicated To The Best Console Of All Time

Back in the day developers would make and send out prototypes for a few reasons. One would be to get their game out to magazines to get reviewed which is great for advertising. Another would be for testing to find out if there are any problems with the game, beta testing for bugs and glitches.
Others were sent out to Nintendo to determine weather they thought the game was good enough to be published or if needed to be censored etc.
