Antelope is good as long as it has been handled and prepared right, if not it is foul and sinewy.
Elk is awesome.
Buffalo is so much better than beef.
Moose is like a gift from the gods.
Rattlesnake is like really chewy chicken.
Caribou has a mild flavor and can be overpowered easily.
Deer is good as long as they weren't around lots of sage brush.
Alligator is like a sweeter chewy chicken, really good in grilled strips or sausage.
Ostrich looks like beef but is really sweet.
That's a pretty good list, I didn't check that website but any of those are going to be a good experience if done right.
Cheers,
