Defo rings a bell about that Defender arcade machine - may try and dig out the copy (under my bed somewhere)

Peter Molyneux (MBE now!) game was Curiousity - Whats Inside the Cube - from Wiki:

On 26 May 2013, 22cans and Peter Molyneux announced via Twitter that the last layer had been removed and the Cube had been opened, revealing the prize video to the winning player that had removed the final layer.[13][14] The winner was identified as Edinburgh resident Bryan Henderson, who was given the option to either keep the contents of the cube to himself or share it with the public.[15][16] Molyneux announced that Henderson opted to share the prize.[17]

According to the video that Henderson saw and 22Cans posted on YouTube the day that the experiment ended, the contents inside of the cube included the ability to be the sole, all-powerful, digital god within 22cans' upcoming release of Godus and to reap a small portion of all of the incoming revenue that is brought in by the game.[18] However, as of January 2015, Henderson has received little to no contact with 22Cans, and in light of recent departures from the studio along with lasting issues with multiplayer, Henderson likely won't be able to collect any portion of the game at all, and once he does, it will only be for six months, or even less if another player overthrows him, who then will take a portion of profits.[19][20] Speaking to The Guardian, Molyneux explained that the person in charge of keeping in contact with Henderson left the company and no one was ever reassigned the position, an act which Molyneux called "inexcusable".
