The Wii U isn't getting much today, as the headliner is NES Open Tournament Golf for the Virtual Console. If you've paying attention, this is one of the inclusions in NES Remix 2, so expect all of those listed games to make an appearance on the Wii U at some point before its launch. You'll also get Blok Drop U, and there's a sale for Runner 2 ($4.99 until March 17th).
On the 3DS side there's The Mysterious Cities of Gold: Secret Paths, Adventure Island II, and Vacation Adventures: Park Ranger. I'm a huge fan of the Adventure Island series, but I'm willing to bet that a lot of people would consider it dated these days.
If you missed last week's installment, here it is.
As for what I'm getting, I think I'm going to double-dip on Adventure Island II, dated or not.
