I guess the real issue here, is the fact that sprites in general age a HELL of a lot better than polygons.
Case in point, many NES games, or hell, for that matter, even old arcade classics like Galaga or Pac Man or Donkey Kong, still honestly look pretty good.
But old polygons? God damn. Most PS1/N64 era games now look fucking ugly as hell. That isn't to say some of them don't still look decent. But a majority are just so blocky with such bad textures....they looked "great" for the time, because that's as advanced as shit had gotten. But the PS2/GC era was a big enough leap over that to matter. Still some not-so-great-looking games, but the polygon and texture levels were high enough by then that old games like Pikmin or Metroid Prime or Shadow of Colossus or Twilight Princess, they still look solid.
But yeah, old sprites > N64/PSX/Saturn Polygons any day of the week. And this is coming from someone who is not, in general, a "graphics guy".
P.S. Sorry folks, but trying to argue that Twilight Princess was a Wii game somehow "Downported" to Wii, is a pretty ridiculous claim to make. It's just functionally not true. Even IF you want to try and say that they started putting more effort into the Wii version and it's control scheme within the last year or less of development, that is literally irrelevant, because the game was built on GC hardware, with GC assets. So no, you're actually straight out wrong. Not just incorrect, but wrong. It's a GC game, ported to Wii, flipped to make him right-handed for the Wiimote.
TP is NOT a decent looking Wii game. It's a fantastic looking Gamecube game. End of story.
