Easiest Zelda? Well, of all the Zelda games I've played, I'd say that
PH was the most easy, for playing it the first time. I thought the bosses were pretty easy, the temples were small and the game overall whas too small (comparing with the other Zelda games I have played). But, I think that I thought it was easy beacuse when you have played pretty many Zelda games, you recognise pretty many puzzles, and can solve them more easier.
