I think that for fish, a beer batter makes them taste great. it is probably not the healthiest of choices but it sure does taste good.

For deer, I cut up the meat and marinade them in a Paul Newman terriyaki marinade. It tastes great. I have friends who are very against eating mule deer due to the sage brush taste, but they even found the meat enjoyable. The marinade makes the meat more tender as well.

For birds....Marinate duck breasts in olive oil, red wine and a little bit of soy sauce for a couple of hours. Take out of marinade and grill to medium rare on hot grill. Serve over long grain wild rice with cooked diced onions, chopped celery and salt/pepper. This tastes great.

For pheasants or any kind of bird I suppose you can't beat plucking and roasting them, I've tried it with ducks to and is good eatin, I would like to with a goose but never have the ambithion to pluck one I tried a few times but gave up.
