Hmmmm "gaminess".....
I know that a lot of times, the "gamy" flavor in much wild game has to do with how the meat was handled after the kill:
Up here - most hunting is done in the fall, with better results ocurring in cool and usually crappy weather. This results in the meat being kept cool. (When we hunt rabbit, we field-dress them, pack 'em with snow, and let them sit, to assume outside-temperature for a while. This allows the fleas to croke-off before retrieving them and bringing them home.)
From what I've seen, most wild boar is hunted down South, where "cold" is highly subjective. If I were hunting down there, I would try to field-dress, quarter, and refrigerate (put on ice) as quickly as possible.
Some people believe that letting the game "hang" for a while improves the flavor. I do not buy-into that.
I will second what Kevin stated about fruit components - one of my favorites that I tried a while back was pheasant with apricots & dates. It was simple, elegant, and delicious.
Same goes for fish - don't let them sit on the stringer & die in warm water, have them soak for half a day, and expect them to taste good!
Like the Nuge says: "Before you grill it (or WSM it..), you gotta' kill it!"
