So far, its pretty good.Just read the eurogamer review. Full score.
Just watched some streams of it. It looks incredible.
However, as much as I want the game, I am very skeptical of buying the Wii-U. For one because the NX or whatver it will be called, might be backwards compatible and will obviously be better than the Wii-U, and also because I rarely ever used the Wii. It only got nintendo exclusives which were few and far between.
Is it "Buy a new Wii U just for this game" good?
I dunno bout all that. I mean they're pretty cheap now, but if you haven't already purchased a Wii U, primarily for this title, a couple years ago, then I'd say you can prolly wait a while longer before diving in.
Only reason I bought it is because I bought a Wii U pretty much for this title and Zelda Wind Waker, and I had to hunt around to find all the cables and parts to hook the Wii U back up, its been like over a year since I've even touched the stupid thing.
