Like I said, if you're expecting to play this in short bursts, then you're choosing the wrong game.
Not every handheld game should be designed to play in short bursts. Some of us like a nice meaty game to get our teeth into for a nice session.
Which is weird as the only way to save in A Link To The Past is to save and quit at the same time (apart from completing a dungeon) which sends you back to a set point. Forcing you to travel wherever all over again.
