I've seen a copy of Jurassic Park Interactive (3DO) with a "Not For Resale" / "For Promotional Use Only" sticker on the front. The game disc repeats these words in a mostly blank red spot on the bottom left corner (right above the black 3DO trademark notice). The game also comes in the third (edit: fourth, as I found another right after writing this) style of 3DO case I've seen - it's like the snap cases, but without the plastic snap. It's like the cardboard cases with a top and bottom shell that you lift off, except that the left edge is connected, so it just folds outwards like a book. It's the same style box as "Way of the Warrior" and "Creature Shock."
I realized that I don't know much at all about the 3DO promo scene. How rare are promotional games? I don't think this was a pack-in. Any clues?
