Going into 2016 I have a bigger backlog than I would like to have, and I'll also be probably getting a few more games as gifts on Christmas, so I definitely need to crack down and finish some of the games. Xenoblade X and Bravely Default will take such a long time though...
P.S. Also as a Wii U owner, I'm ashamed I didn't get Mario Maker. I'll make it one of my first purchases in 2016.
