To compare games from diffrent eras, perhaps at the end of this you could subtract the 'Worst game" votes from the "Best Game Votes" and divide by total number of votes.

So for example a recent Year X had 45 best game votes and 12 worst game votes.
It's score is : (45-12)/57 = .579


An older game, Year Y had 5 best game votes and 2 worst game votes.
It's score is : (5-2)/7 = .429

Just a thought on comparing older and newer games with different amounts of people around that actually were involved.
