i think n64 is cool because it is unique and recognizable. i’m unbothered by the sludginess of the average NTSC N64 game’s visuals (internal scaling using VI is gross, though, see e.g. Body Harvest and Genki’s MRC: Multi-Racing Championship, not to mention far too many poor PAL conversions), and in many cases (Iggy’s Reckin’ Balls, Banjo-Kazooie), the sludginess is vital to what works about the game
what is a “PS5 game” but a PC game that got ported to a PS5. n64’s got some flavor in that chew at least
