I really need to get more to my Wii U games. I've been playing Smash quite a bit, but I've been neglecting Splatoon lately. Plus I downloaded Earthbound and Superstar Saga both, but only barely started Earthbound and haven't even started Superstar Saga. I'll probably get Partners in Time after I beat Superstar Saga. And then I'll finally have an excuse to play Bowser's Inside Story and Dream Team, both of which I have but have only barely played.
As for my 3DS . . . whoo boy. I've got almost 500 hours in ACNL, and over 100 in several other games like FEA, KIU, and Pokemon Conquest. And yes, I got Xenoblade at launch. I haven't been playing it completely consistently, though, there were at least a few times where I only played once or twice a week.
