Zelda, without a doubt, though the other three are great choices too.

Zelda one, haven't really heard of the other 3 games at all.

Is there a reason for your stance? 

Just curious.

Botw for me, although I do intend to get all of them eventually.

Why would I buy an overrated piece of garbage (Shovel Knight) over BotW?

Zelda of course, but I will be picking up Fast RMX and Snipperclips day 1 on the Eshop and wouldn't be surprised if I end up spending more total time playing those games since they offer fun local multiplayer. 

Zelda is one of those things you beat and then don't go back to for quite a while until you've forgotten it a bit (at least for me), while the others I can go back to every other month

I also only ever tried Shovel Knight on PC so may give it a shot on console 

Zelda easily - considering it looks like one of the best games of the last 5 years, and I don't really care for the other games, even at $20 a piece, especially digital only..

I mean Fast RMX does interest me, but Redout will cover my futuristic racer. Looks like it's $35 or so but at least it'll be a physical media release, which I strongly prefer, especially when it comes to Nintendo.

I will probably, however, download I am Setsuna, because it looks like a great game that I am willing to overlook the price and the digital download. It reminds me of a lot of old JRPGs with some ToS mixed in which I love. I also may download Little Inferno just to have a quick mindless pick-up-and-play game to balance things out at launch, plus it should only be 10 bucks or so.

Zelda, Fast RMX, Snipperclips, I am satsuma.

Ports vs a New Game.......

BoTW.

While the other 3 games look okay, their nothing really special.
