I heard that possum can be good if you trap them and feed them nothing but cornmeal and water for about 2 weeks, and get them away from their scavenger diet. I'll try to go back and find where I learned that. But I can see where it could work if it is legal to do that in your area.

Ks_Sniper - I have a book from 1972 that is an Outdoor Life book called the "Complete Outdoor Encyclopedia." It talks about the range, food, and edibility of a lot of different game animals, plus a lot of other info.
