Hello! Before I start, no, this isn't an important suggestion. Is it a funny one? Yes. Yes it is.
Plenty of the textures in SN are 2K, and look REALLY crisp. But for those of us with an overkill computer, and VERY observant eyes, i'm sure upping the resolution a bit wouldn't hurt, right? (totally wouldn't.)
This 4K Mode would be a "Free DLC" of some kind, which means you'd have to manually download them yourself. This lets players who want to play normally get their wish, and players like me get their wish without much intrusion.
Also this is technically fanservice, but, i'd love to see what SN looks like in the maximum possible quality. Thanks!
