Speaking as a hunter, your assertion that northern climates (I live in the north) produce more game is false. Deer populations, to use one example, thrive in warm temps. Also, compare the African savannah and its abundance of game animals to, say, northern Canada. The real reasons are probably topography and game habits. The north is generally pretty flat and the ground is often frozen, making travel easy. And in cold temperatures, game often clusters together for warmth and follows predictable movement patterns because there are only so many places to find food. And finally, snow makes it easy to track game of any size. These are all important in modern hunting too. Not much has really changed in that regard.
