Just purchased Earthbound about a minute ago. Before that, it was Xenoblade Chronicles on the VC in February 2017, so you could count that as my last Wii game as well. The last time I actually purchased a Wii U game was way back in November of 2015 when I bought Splatoon and Xenoblade Chronicles X. I do have Star Fox Zero, which we got when it came out in April 2016, but that's my rooommate's game, not mine. I didn't realize it had been so long since I had bought a Wii U game, because I have actually been playing the system quite a lot.
I might still get Tokyo Mirage Sessions, but only if it goes on a major sale. Not paying $60 for it.
