Universally regarded as the weakest of the three (and it wasn't made by the same team as the others).
Yeah, I know... Counterpoint: I still get to be Batman again! The Dark Video Game Knight Returns. =) At $20 though I'm leaving my cowl hanging up.
Update - Not that I consider the source reliable, but this sure is coincidence:

I certainly will pass now, this was only a "So, I hear this is a big deal?" consideration. If you or Aaz told it it was super worthwhile I'd have been intrigued, but otherwise... meh.
Other than these, you might want to check out the WiiU's virtual console. It's the only one that has Earthbound.
WARNING: INCOMING RANTI saw that, and I do have $5 free from my Wii U digital deluxe points and considered it, but after my 3DS virtual console experience (I wasted a lot of money on games I already have/have played/won't play again =) I've made a philosophical decision to only invest in digital content original to the platform or my play experience. Why waste the money/time/hard drive space otherwise? It would help if I got more value for my money, and use out of my Nintento Network ID, and was able to play my 3DS Virtual Console games that crossover on the Wii U and vice versa, but of course not. It wouldn't bug me if there was a real physical barrier other than the old fashioned concept that rather than paying for the license to the content on my account, I should pay for it on each individual device (even though that's almost an arbitrary, if not greedy, distinction at this point). I bought Mega Man 2 for my 3DS not too long ago, and I have to pay another $5 to add it to my account on the Wii U? Same thing with not getting digital rights, for flexibility and convenience, to games I bought hard copies of (I'd play a lot more 3D World if I didn't have to switch it out with Mario Kart =). What's the point of the ID then? So my Mii's match and I know
how many times I've bought Mega Man 2? Nintendo is getting there with this stuff, and the stuff unique to Wii U is evolutionary if not revolutionary, but that gets undermined when some of the basics feel neglected or retrograde. It's frustrating to watch them inch along at their own pace, to come to the same conclusion, instead of just doing the sensible thing now ( and it's INSANE to me that they allegedly don't pay attention to what the competition is doing, that's some doomed to fail bad business practice right there). Especially when my account/devices aren't communicating about what little they are supposed to be on the same page about and it's like one hand doesn't know what the other is doing. /rant
The game expects you to 
Oh ho ho... Expectations: RAISED!
