I've got all the golds and stars in the 50, 100, 150, and mirror cups in Mario Kart 8. Still waiting for the 2nd set of DLC for that one.
I'm working through all the time trials right now, trying to beat the times that Nintendo set.
Other than that I'm still dabbling in Hyrule Warriors and Super Smash Bros. on the Wii U and Persona Q on the 3DS
