The most complicated game ever?

A hard thing to decide, because the criteria is so fuzzy. What defines 'complicated'? Confusing, Baffling, or Incomprehensible. I would probably throw in some element of 'surprise' in the sense that what really happened only becomes clear at the conclusion of the game.
One candidate would be the Bronstein - Ljubojevic game from the 1973 Zonal. I've seen this appear in a number of game collections and in each there are pages and pages of analysis. Bronstein himself devotes 17 pages to this game in "The Sorcerer's Apprentice", although that utilises analysis done by Timman and Keres in other publications.
Interestingly when I ran it through Fritz it seemed to get most of the moves played, but it was the assessment of the position that fluctuated wildly. So that may be another definition for complicated, 'If the computer has no idea who is better!'

Tim Taylor in his book on the Bird's Opening makes much the same claim for 2 games with Mestel in Ftrom gambit lines, alos claiming that the computer switches wildly between favouring balck and white, sometimes even without a move being played as it analyses further and further
