Completed Mario 3D World.
Currently playing "Remember Me" on PC and I'm actually surprised by it. The reviews didn't seem too favourable, but, 2 hours in and I like it so far.
On Wii U, mostly playing Mario kart 8 still, with a little Scram Kitty and Wonderful 101 (just a few more Pure Platinum medals and unlocks for 100% )
Just started Transistor on PC, and playing a little Killer Instinct on X1.
Did you play through the secret worlds too?. I think some overlook them not realizing they exist!.
