As mentioned I got these before I had relevant systems because they looked cool. Got a bunch when Toys R Us closed also. The kids use them for goofing off IRL and they still love Disney Infinity to boot.
I still want to get Yoshi, DK, and especially Banjo-Kazooie!
I have no plans to use them, so I'll keep them in the box (just in case I ever want to sell them someday).
