A:AnswerNo it is not, as of what I know there is no Link to the Past HD unfortunately. This is a remake of the original Links awakening and in the Zelda timeline this game takes place after a link to the Past. But this game is great and I do highly recommend it. I would love to see Link to The Past HD happen though. And Skyward sword HD is also coming pretty soon so maybe he'd like that one too.
A:AnswerIt means that it’s a digital copy of the game that gets downloaded to the gaming system. There is no disc/chip. They give/send you a code to enter and follow the steps to download the game permanently to you system. 1 benefit is that you do not need to enter a disc/chip every time you want to play.
