This makes no sense to me, and I hope Kojima has gotten complaints about it. He claimed that Ground Zeroes was the equivalent of the Tanker sectiom of MGS 2, which was in the beginning of the game, and took about a half hour to beat.
Everyone figured he had revealed it earlier to continue hiding the existence of the actual game, The Phantom Pain. Now it seems he is selling them separately. In that case, he should have been marketing it like Capcom did for Dead Rising: Case West, something completely separate. I'm a die-hard MGS fan, and I'm confused, so I can't imagine how the average consumer feels. Are they the same? Are they different? Does the full retail game, Metal Gear Solid V: The Phantom Pain, include Ground Zeroes, and if not, why?
