I've been playing Windwaker HD on my brother's Wii U, I'm enjoying it quite a lot. I've already defeated the first boss.
I've also been playing A Link Between Worlds on my 2DS XL recently. I'm a bit stuck though.
I also have Triforce Heroes, which I play every now and then. Not many people play Triforce Heroes online anymore, which means I have to do the adventure solo, which is at least 10 times more boring.
I also have a NES Mini, which means I can play Zelda I and II as well.
