I was very satisfied with the more mature Link, and the nicely done graphics. It just blew my mind how much content they got onto the little GameCube discs with graphics like that. I would also just like to add that this may not be as brilliant as Ocarina of Time, but being able to see the new visions of Ocarina of Time areas almost makes up for that, as well as the new items and special move systems. Fantastic game, worth a buy or a very long rental.
Twilight Princess was just what I was hoping for. It is almost exactly like the original which I also loved. A lot of sequels try to change the gameplay too much and end up ruining the game. The twilight wolf addition to the game was all the change needed to make Twilight Princess the perfect game. I love this game and I strongly suggest you give it a try.
