Kirby Super Star Ultra is pretty good. A unique approach with it's anthology-based structure and this allowed it to come up with some pretty creative modes in the form of Great Cave Offensive and Milky Way Wishes and both modes kinda make me wonder how a Kirby Metroidvania would work. There's some foundations here for that.

Then there's Meta Knight's Revenge, which was an enjoyable high-speed mode. I actually came quite close to running out of time in some parts. Speaking of high-speed, Gourmet Race is a classic. I did play that one in the original and i feel it controls better here?

Spring Breeze and Dyna Blade are fairly standard Kirby adventures. The former is just a remake of Kirby's Dream Land. So fun but nothing to write home about.

Ultra did add some new modes, mainly Revenge of the King and Meta Knight Ultra. While Revenge of the King is a good "hard mode" version of Spring Breeze (and even introduced Masked Dedede, this whole time i was being gaslit to think that was a Triple Deluxe thing), Meta Knight Ultra is fun at first but it's just redoing the original modes (minus Gourmet Race and Great Cave) as Meta Knight. The only difference is you fight Galacta Knight at the end but honestly i would've preferred it if it was more original.

As a whole, Super Star Ultra is very fun and i wouldn't mind if they did something like this again. Maybe now that the series has fully gone 3D, they could do a "3D Super Star" or something.
