So I did pick up Samurai Shodown recently, and it's quickly changing my opinion about fighting games on Switch. Really glad I picked up the Hori d-pad joy-con on sale too.
I've only played a couple hours of training mode plus one playthrough of story mode, and outside a few rare slowdowns/frame drops (usually during animations not affecting gameplay), the game looks and runs great. Anyone that's interested shouldn't have much to worry about.
Wouldn't mind hearing some feedback about other great fighting games on Switch. I'm already looking at Guilty Gear 20th Anniversary, Street Fighter 30th, Samurai Shodown NeoGeo collection, Dragon Ball FighterZ and every KoF available (though I'm hoping they'll get a physical collection too). On the fence about Mortal Kombat 11 after everything I've read/seen.
Also, can we please just appreciate the SamSho Switch box art compared to the lame original release:
How many games actually make this effort to not only differentiate Switch box art, but improve it.
