On the one hand, if it's half as good as LttP then it's probably worth buying a 3DS for.
On the other, the footage they've released makes it look painfully like a rehash by people who think LttP's appeal comes from its mechanics, its tiles, and its enemies. The most exciting thing in the video is Link turning into one of the hieroglyphics from the beginning of Wind Waker; I am hoping that this is a useful power that broadens the areas you can explore instead of something like that zippy top thing from TP that you use on one dungeon and that's pretty much it.
Me, I'm a whole lot more curious about Bugs vs. Tanks -- because it is an Inafune game, it is not a sequel, and it is called Bugs vs. Tanks -- than any of the announcements that are actually grabbing headlines.
Also, hey, a legal way to play Earthbound without spending $600 on the copy at the used game store.
