So, perhaps the key to unlocking the 2006 clue, when and if it is released, is researching every questionable and/or suspicious word and fragment within the clue.
Last year's was pretty darn good. I went too far into my research (titles of songs on the album "Sargeant Pepper's Lonely Hearts Club Band"). Perhaps I'll stay a bit closer to home this time around.
Then again, if the mastermind reads this, then he'll make the answer to the clue as far out as the research I did last year, which would then defeat the purpose of me changing my research and clue unlocking patterns.
So, in that case, research is key. Just be careful. Game objects, player quantities, anything, will be fair game for encoding.
