I did a bunch of research in the past, including links to studies on the subject with a number of universities on various game department sites. Wish I had some of the links for you, but they all agreed with my personal experience. To sum it all up succinctly, it was found that there was benefit to aging game (most studies involved venison, but some elk), 5-7 days at an optimum temperature of 40 degrees F. Higher temperatures shortened the optimal time. There was little to no benefit cited, whether for toughness or flavor, in aging longer, but some real potential problems in aging longer at higher temperatures.
