AoL is a great game! I would rank it #2 in the entire series.
But the reason I love it is probably the reason most people dislike it........it's difficult!
Enemies are tough, puzzles tricky, and there is alot to uncover. There are no Midnas, Navis or any other "helpers" to hold your hand and guide you throughout the quest. The game requires a great deal of effort that alot of gamers aren't willing to put forth.
But if they dedicate themselves to the game they will begin to enjoy it. They can really appreciate it. If and when they do beat the game, they will have a feeling of accomplishment unlike any other!
