Game Freak shouldnt do a gen 5 remake. Do not remake Pokemon Black & White or Black & White 2.
Instead, port the games onto the switch, and make Black & White 3.
I think shitting on modern pokemon games is annoying and people going "buh they couldnt do the remakes justice" would be unhappy with literally anything, because Pokemon fans are gluttons who would be unsatisfied with the entire riches of heaven, but I do think the games dont need to be remade. Just yknow, playable. For less than 100 dollars on Ebay.
