I agree I think, the art style is extremely bland now it started with Mario 64 which is one of my top 5 favorite games and I attributed it to the N64's lack of power.
The music has gotten worse too, too much steel drums etc... I don't find it memorable.
Rayman Origins, and Donkey Kong Country Returns is way better than any mario or little big planet imo, in both music, level design and aesthetic.
You can say it's nostalgia, But I like Skyward Sword, I like the Newer Final Fantasy's, I Castlevania Lord of Shadow, Donkey Kong Country a lot. The newer mario particularly the 2D ones are just bleh in comparison with 1-3, world imo.
