Mario Kart 8 - i still own the original, not sure why at this point. it is a great remaster though so im glad i got it.

Overcooked! - i bought it originally on PC before the Switch was unveiled. it was always hard to do multiplayer though since i didnt have multiple xbox controllers. but with the switch i had two pairs of Joycons that could be split into four controllers. and that just mad everything easier. later i got Overcooked! 2 on the Switch and didnt even bother with the PC version

So you believe there will be a MK9 on switch? I think if anything we will get a Diddy Kong racing sequel because that will be different enough, and mk9 won't be out until their next device. But who knows?

Mario Kart 8 and eventually Hyrule Warriors (triple dip).

That is all, as I only used my WiiU for Zelda games.

Mario Kart 8: Why not? I got a lot of mileage out of the WiiU version and this one was not different.

Zelda: Breath if the Wild: getting the WiiU version was a stupid mistake to begin with, and I ended up getting BoTW around a year later to complete my collection.

I will likely double dip in DK:TP if there is a price cut at some point.

I am guessing because the PS4 and XboxOne version just released last year November. Sooo hopefully we do get an announcement next year.
