Hmm...this has to be one of the weirdest and probably one of the farthest away from the intention of the hint, but I'll thr
Everyone knows about Dave's "hints." Someone mentioned a while ago that the Opah is sometimes known as the "King of Herrings." Red Herrings...Dave's hints...Dave's herrings...could this be a ploy to get us to actually dissect his signature? Maybe he WAS actually dropping hints, we just didn't realize it. I haven't been watching Dave's signature too much, but based on what I saw posted earlier about Six, Five, and Four...Six and five are mentioned in the quote that he has up there (woot, superfluous adjectives), and four..."To the four: awaiting a few more.".
...I'm just going to stop now, that's not it. You know you've gone crazy over a game hint when you analyze every word in Dave's signature.

Although it may point to him somehow, it's not in that way.
Though...
moonfish...Phoenix/
Mars...
NASA...Outer space, anyone?
I'm fairly sure that it has to do with the fish itself. It's the fish and not some other object that could embody the same hint but would be more obvious. Like last year, with the tortoise and the hare referring to a race...if they wanted to make a race game obvious, they could have easily given us the coords for something NASCAR-related.
So the Opah might have some quality that other things obviously have...the GDC just didn't want to make it too apparent.
I can't wait for the next hint; we
might be able to start piecing things together.
