Probably Smash

The gyro control, aka, controlling the aim by moving the controller, worked fine, although both that game and Splatoon came out at a time where gyro aiming still had to prove itself, and both got criticism for it, although the criticism for Splatoon quickly disappeared after players really gave gyro a chance. And I insist that the problem with Zero wasn't the gyro, but the double screen setup. You can technically play using only the cockpit view, which is the view on the Gamepad, but iirc you could switch the TV view to that too like in SF64. But one, I don't want to play on cockpit view and two, I neither want to play switching the view on the TV, nor switching my attention between the TV and the Gamepad. The whole problem of the game is that the devs deliberately made the full ship view inaccurate to force us to use the cockpit view, because Nintendo just *had* to show us how great the second screen gimmick on the Gamepad was. Gamepad was great in some games, in that one it was not only a miss, it was a shot on the foot.

On a somewhat related subject, though, there is a last gen game that I want ported to the Switch more than any of the remaining games trapped on the Wii U:

Fire Emblem Echoes: Shadows of Valentia

WWHD, Yoshi WW a close second

The two best games on the list are Mario Maker and Splatoon. Both of these games were made obsolete by the Switch sequels. Basically the Switch made the Wii U completely obsolete, and the Wii U wasn't a popular system in the first place.

Does the WiiU version do something different compared to Ultimate? To me they played very much alike and I have no reason to play the WiiU version over Ultimate.

Brawl, which I despise and think is complete trash entry in the series, at least had the single player subspace and different slower mechanics making it stand out and give reason for people to keep playing that version. But way would someone play Smash WiiU over Ultimate?

Definitely Mario Maker.

Not only that, but both those games were basically dependant on the servers that got shut down.

So those two didn't just got obsolete, they lost basically all value aside from a collection perspective.

Sad how the online focus can both make a game great, and also mean it eventually will lose all or close to all of its value.

Gladly there are people trying to keep those kind of games alive by being back online.

Yoshi. It was a fantastic game - almost worthy of being spoken of in the same breath as the original (which is my favourite game ever).

I am not someone who enjoys any form of motion controls and will thus look to actively avoid it, unless it's VR.
If I can't turn it off, the game is not fun to play.

That's a personal preference.

I detest motion controls.

Ok that's fair.
