Update: The code has been redeemed.
(^_^) A not-so-mysterious wanderer had deciphered the underlying meaning of a rather familiar grouping of structures composed entirely of text (as opposed to blocks).
LEGO The Hobbit 9 J 2 F _ _ _ _ _ _ _ _ _ _ _ _ _ _ 1(BE) 5(08) B(CF) A(03) B(0C) 9(8E) E(38) 3(8A) A(AE) 2(DF) 1(3C) B(EF) 8(3F) 6(8B)
To all solvers of previous puzzles: self-restraint is
unnecessary. If you have correctly determined the solution to a given riddle, one should not waver in redeeming the corresponding game code (it rightfully belongs to you). Even if I were to provide non-free GOG (20-character) gift codes (which, in the not-too-distant future, is likely to occur), this opinion would be maintained.
: ) The puzzles serve as instruments to activate specific areas of the human mind (
"so that we may identify the hidden capabilities of your species, prior to acquainting you with our colonization procedures, and harvesting your..." *nervous laughter*
"oops, I had forgotten to disengage the covert-thought amplifier - how embarrassing" *profusely-exudes a viscous, green-tinted substance*).
