I just completed Banjo-Tooie (it was pretty incredible, as I anticipated), so now I plan to set my Wii U back up and work on getting all of the stars/stamps/vehicle parts in Mario Kart 8 as well as playing Earthbound some more.
I'm also replaying Donkey Kong Country Returns (now on 3DS thanks...
I'm playing Super Mario Bros. 3 for the first time. Four levels in and I can already see what the big deal is.
I'm also playing Golden Sun: Lost Age. Started yet another new file in hopes that I'll actually finish it this time.
Super Mario 3D World
Pokemon Y
I'm trying to get into competitive play in the Pokemon world, and I completely suck. Spent the past two days just trying to breed a got dang perfect Honedge. It's weirdly really fun though.
