I'm generally against intentionally disguising, masking and burying the flavor of game meat. That being said, brines, marinades and seasonings are all tools that, used properly, can enhance and augment meat flavors. I can always appreciate simple straight forward approaches. My favorite BBQ place in West TN rubs the meat with salt, smokes it and adds sauce -no trickery. I am much more interested in straight forward recipes that than recipes that call for burying the meat in piles of bacon, cream of mushroom soup or Italian dressing. At the same time, I really enjoy using game meat for ethnic and and authentic traditional food. Be it German, Mexican, Indian, Cajun or American other comfort foods. I have no desire to eat game meat the same exact way every time. Once you understand how to work with game meat, its really interesting to take traditional recipes, be it complex or simple, substituting game meat.
Brines and marinades are great tools, but, IMO, they should be done using whole food ingredients -made from scratch with no processed foods with the ultimate purpose of making a contribution to a interesting/flavorful/desirable outcome, not a means of disguise.
