Topic: 3DS games that should be ported/remastered for Switch.

As for first party:

A Triple Deluxe/Planet Robobot double pack. Of the two I've only played Robobot, but it's one of the best Kirby games I've played, so I'd be down for an HD port.

A Link Between Worlds. Just never managed to get around to it on 3DS, so why not Switch?

Ever Oasis. Came out so late in the system's life I've never played it.

Luigi's Mansion. Itself a port to 3DS, why not port again.

I wouldn't be opposed to a 3D Land port either (at least as part of a second "3D All-Stars" like package with Galaxy 2).

As for 3rd party, Dragon Quest VII & VIII, Tales of the Abyss, Ace Combat: Assault Horizon Legacy, and the Senran Kagura games would be good picks, but any HD remasters on the 3rd party side of things would likely end up on Steam which is where I'd be more likely to get them.

Ever Oasis, the first Taiko no Tatsujin 3ds game, all of the missing DQ games (hoping the DS ones all get a remake like III), the back half of the Ace Attorney games, actually all visual novels that are on 3ds (no reason not to), the Zelda 64 remakes, all the fire emblem games locked on 3ds, and the project cross zone games. Oh and Fantasy Life and Street Fighter IV (cause Capcom is being Crapcom).

That being said none of that will likely happen except maybe some of the DQ games.

Metroid: Samus Returns HD (even better if it includes Federation Force)
Tomodachi Life HD
Hey! Pikmin HD
Poochy & Yoshi's Woolly World HD
Donkey Kong Country Returns HD
Ocarina of Time HD + Majora's Mask HD + Triforce Heroes
Luigi's Mansion 1 + Luigi's Mansion 2 HD
and all the Mario & Luigi and Paper Mario games.

I almost put Chibi-Robo, but the good games were on Gamecube, DS, and Wii.
