Now, for this game, it is highly unlikely, but Melee deserves to be preserved better than an emulated version on a Switch 2. Now a future version on Switch 2 is not so bad, but it is locked behind a subscription service that not many people can afford. This site is not the preferred way to address this issue, but I still wish Nintendo would at least release physical and/or separate digital or collection versions of the classic games instead of being exclusive to Switch Online.
Even if this is 95% not happening anytime soon, I am still hopeful that Nintendo could port their games on PC in any way, maybe GOG. But still, I believe one of the realistic outcomes for Nintendo to port some of their games on PC would be to make their very own digital storefront,
a PC eShop, similar to Steam, GOG and Epic Games, but with Nintendo games exclusive to their storefront.
