I've always tried to sneak up on game as much as possible but not at the risk of spooking them. Deer are a fun challenge to sneak up on and turkeys are a blast. I've never felt the need yet to sneak up on a bear though. I can see how a person would practice more skills when stalking dangerous game and prefer to shoot them from longer distance. That's just plain common sense. And especially if the dangerous game knows you're there.
