Higher-tech games are not objectively better, though that's a very common fallacy among "hardcore" gamers and hardware devs. You can do things you couldn't before, which opens up new kinds of gameplay, and it's certainly nice when games are extremely pretty, but the indie revolution of the last decade should have conclusively killed the idea that tech trumps gameplay. Just for one example, Spelunky essentially founded the "roguelikelike" genre and played a huge part in kickstarting the indie surge, and it (at least in its first incarnation) could just about have run on the SNES.
