I didn't buy it, but it was probably necessary.
I recently got back into Zelda after falling away with the SNES. I've had to look around to collect the games I've missed. From what I'd read, it seemed the GameCube version of TP was the superior version, so I set out to find a copy. Of all the Zelda games I had to buy physical copies of, it was by far the most expensive to acquire. We have a regular Wii, so I could play the disc. If you didn't have a Wii or GameCube you'd have to get one of those just to play it.
So, for a generation of kids who want to play TP, this remake is much easier. I had a lot of hoops to jump through to play this particular title.
