If anyone in the UK hasn't seen this yet it's basically the story of how tetris came to be and how Nintendo gained the right to it. Has everything you want to know about the game and how many people had rights to it or thought they did. http://www.bbc.co.uk/iplayer/episode/b0074pz0/Tetris_From_Russia_with_Love/
Nice one GodofHardcore just watched it and didn't even check if it was on YT but none the less a good watch especially as in my case don't know anything about tetris apart from my sister having on her gameboy back in the day and me playing the odd time.
