I disagree, but your odds of having a bad time with game meat are much higher. I liken it to the early days of craft beer. If you wanted an acceptable beer that wouldn't wow you, but never surprise you, you could always drink budweiser. But if you felt like playing six-pack roulette, pick up your local microbrew. Could be awesome, could be terrible, you won't know until you've taken a drink.
Domestic goose is better than wild goose, but grass-fed elk (that is, ranched elk) just tastes like beef. Likewise with grass-fed bison. Truly wild elk has that gaminess to it that I really appreciate. I've a recipe for venison burger casserole that is utterly flavorless when made with ground beef. Bear sausage is only good when its heavily mixed with actual pork, and spiced to hell and back.
Deer and pronghorn that graze on sagebrush actually taste sagey. If that's your jam, its fantastic.
