[manyquestions]

Notice that the use of cities, roads, and states, regardless of which specific cities etc. they were, prompted an incredible number of Google Maps (and other map-sites) searches for a pattern in the cities. Perhaps the clue is simply the fact that they are cities, and that so many people's first reaction is to look for map patterns. Couple that with this logic from hint number one: "moonfish>moon>outer space," and you get something to due with satellites. Maybe it's a far more strategic game than many other people have suggested, involving some kind of coordination with a satellite object to direct attacks on key points of the field, possibly with a RISK-like "global domination" theme.

It's a bit of a stretch, I guess, but it'd be pretty cool in my opinion.
