I already own Minecraft digitally, but I'll get the physical disc for my sister so we can play together. Already got Tokyo Mirage Sessions and loving it. In the "wait for a price drop" camp on Force Awakens.
I forget, does Terraria support pointer controls? Because that will get me to pick it up as well. I feel like I asked this before and feel like the answer was yes.
Other than that I plan to pick up some games I missed like XCX, Star Fox, Mario Maker, and Splatoon. Though the latter two may wait longer because I want to hear if they will release up-ports to NX with added content.
