I can understand why someone would age a beef because the fat is flavorful from the feeding methods and the meat is properly marbled, however game animals have fat that goes rancid quickly, and connective tissue and glands that impart a terrible flavor to the meat the longer you leave it in there. THE worst game meat I have ever eaten has been "properly" aged. Just a personal opinion, but I would opt to get the skin off the animal right away, get it quartered out and cooled right away, and butcher it myself before the meat even had a dried "skin" to it. Tenderness for me is a reflection of how long you cook it. It needs to be medium rare to rare and it will be tender and flavorful. Flavor has to do with several things:
1. What the animal eats
2. How old the animal is
3. How much stress the animal was under before it died
4. Lastly and most important: How quickly you got it cooled off and clean after the shot and got the hide, fat, and connective tissue removed from it.
People insist upon putting pork or beef fat in with ground game as well, personally I like to add any fresh fat right before cooking because fat goes rancid and freezer burns before whole muscle protein.
I've completed the experiment before and it is easy to do at home. Age one hind quarter in the method you describe and butcher one hind quarter right away...I tried it on three different occasions, and the un-aged meat was by far better flavored and less "gamey" IMO, and both were very tender because they were cut and cooked properly.
