NG score stuff
I think all of you read into it way, way too much.
It starts out as a tremendously flawed score because it is against the same rating scale as Flash movies. Secondly, the NG audience is extremely narrow minded, and too many of them feel they for some reason have the ability to judge Flash elements rather than just rate based on their actually enjoyment of the game.
Next, you have scores heavily weighted by favoritism. More popular authors get higher scores and it's as simple as that. Go to any other site on the net and any Flash game has a chance of fairing much better than here on Newgrounds.
To top off the flawed game scores, you then have the people who voice their opinion on the content once every day which completely butchers the validity of the score.
So, my point is, trying to actually make a set in stone line item or graph or whatever to predict/explain NG scores would be as hard as making one on winning the Lottery.
