Here's an interesting idea, one that could apply to all the past years of Treasure hunt winners as well:
Usually when a submission is honored as winning a part of the treasure hunt, it gets front page for a week or so. The whole reason for that, is so that underappreciated movies/games get the spotlight for a little while. But then that treasure hunt ends, and they are basically forgotten again.
What if the submissions honored with being a Treasure Hunt winner had a special award added t it's page.
A little pixelated treasure chest simliar to that of UotW or RCP?
I think it would be pretty cool. And a symbol that new generations of Newgrounders would be able to see at any time, rather than digging up old posts about the old winners.
