Deer we normally country fry. Marinade in Worcestershire sauce, batter up in flour and milk, season with salt and pepper, fry until golden brown.
Dad has gone out west to get elk a couple of times. We use that stuff as a beef substitute in a lot of recipes: elk burgers, elk chili, elk vegetable soup, etc. its all around awesome - full of flavor, but lean and not greasy like beef burger.
Also had a lot of duck this winter. Best thing we found was marinading it in Allegro (no, not Allegra-D the medicine!). Cut them in halves/thirds, wrap in bacon, peppers and onions. Grill until the bacon is fully cooked, duck is great on the rare side.
