My grandmom use to make an awesome Beef heart and kidney pie ( She and my grandfather were born and raised in the UK, came over here after WWII) Loved that stuff...she would actually make extra so my mom and dad could take it home for me...... One of those childhood foods id love to have again, but never will 
Would love to try blood sausage.....but cant find it around here...you would think with all the Pennsylvania Dutch roots around here it would be easy, but its not
Those meatballs sound incredible, and i have about 50lbs of venison burger in the freezer....you have a recipe Danny?
Just make them myself really, ground venison and pork shoulder, mixed herbs fresh pressed garlic cloves and breadcrumbs.
I make big fat meatballs about 2 inches in diameter, and then fry them in a fairly dry hot pan until lightly charred. Then cook them ina tomato and red wine sauce in the slow cooker for a good few hours, then shred fresh basil over them and parmesan, they are pretty special with just a glass of wine and some good bread, or with pasta.
My oldest friend is an RSPCA Inspector pretty close to me so we don't really have an issue laying hands on fresh venison, we live in the sticks and he usually has to shoot a traffic damaged one fairly regularly.
Also means we can get shoulder which is ordinarily smashed by the bullet
