1) New Super Mario Bros. U
2) Pikmin 3
3) Wind Waker HD
4) Wii Party U
I own disc copies of #1 and #3. I've never really been into Pikmin but nearly everyone loves those titles. Should I get Pikmin or a digital copy of one that I own just so I don't have to use the disc? #4 is out of the question for me

I don't have to choose now, so no rush.
