GoldenPhoenix - Read that right before I started playing, but haven't noticed anything yet. Only just got to Kakariko Village. About to dive into more of it today.
Ceric - Animation is good. I really love the improved art style, and there have been many times where I've been impressed by how it looks. It's like a really distinct memory that's better than you remember.
"Hey, Listen" is still in there.
Hyrule Field is still barren.
3D is really nice. Particle effects are where it stands out the most, though I didn't realize how many moments there were in the game that are gimmicky 3D moments. There are a lot "tossing things at the screen" and "things coming out at you," though with the way the 3D works on the 3DS (more like a diorama that you're looking into as opposed to the screen reaching out to greet you), it's not mind-blowing. The 3D is just really nice.
It's been several years since I've played it, but I did get to Hyrule Castle Town in about an hour, which I feel is outrageous.
