The smart money is on Checkpoint from Data East. I mean the clue says checkpoint in it! What else could it possibly be?
Though if I had to take a second guess id say Gilligans Island, since it sold 4300 units.
Perhaps a Gilligans Island, checkpoint 2 pack?
A little late to be making these kind of posts when they already showed off HS on the stream.
