lol kirby looks exactly the same to me

There's a lot more detail there but it's gonna be hard to improve too much on these cartoony characters.

Brawl looks better O_o

Ha actually I would say that Mario's clothes in Brawl look much better due to a more detailed overalls texture that actually looks like it's made from denim.

Fox looks even worse now? :o

I dont know if Brawl was simply amazingly good looking on the Wii, or this is just a lazy HD remake. I mean the game does not look good by any HD standards...

Brawl has more model detail that U. Its easily visible on Fox,Link and Mario

I liked Brawl's more realistic style better, but that doesn't mean I don't like SSB4's look. It just took some time for me to get used to it.

Better resolution and more details... that's it after the first look.... the scenario seems to see the same.

I need to see a video in gameplay for better opinion.

Edit - A big difference... SSBU don't have AA.

SSBU looks better although Brawl has more realistic art style.
