New Super Mario Bros Wii ....when I saw it had 4 player coop I cried with joy lol

...but seriously I'd say Odin's Sphere. I love Vanillaware art style.

wonder boy remake.

Playstation : Legend of Mana , Saga Frontier 2

Xbox 360: Dust an Elysian Tail

Xbox One: Ori and the blind forest, Cuphead and Rayman Legends

Ori is an absolute stunner for sure.

Some others that rank high for me:

Kirby's Epic Yarn

Muramasa

Puppeteer

I'm surprised more people didn't mention Wonder Boy: The Dragon's Trap. It's easily the most beautiful 2D game imo.

They're remaking Streets of Rage 4! It still looks good, but I think I'd rather see them remake another cutesy game.

you should check out Muramasa: The Demon Blade with hd textures on dolphin emulator. missed opportunity for a remaster.

I had no idea this was even a thing. Looked it up and wow, gorgeous!

I know it's a weird pick (or is it?) but Celeste, that game is gorgeous. That! Or! Gris! Gris is breathtaking.

HD textures in emulators? Yeah.

My guess is, by the time BotW2 realeses, Yuzu will be so stable that shortly after realease there will be HD texture packs that improve significanlty how game looks, especially with popularity of ESRGAN AI generated higher res assets that preserve original art, just making it more detailed.
