Planet Robobot is the last good Kirby game as of yet, and somehow managed to create an interesting new spin on a series that has been done to death in a singular style, while also making the basic core gameplay elements of any Kirby game still feel really fun and unique. Planet Robobot has great level design, great abilities, and is just a really solid Kirby game all around. I also think that it will be pretty much the last hurrah for 2D Kirby, as Star Allies sucked and it seems we're going to get a big change of formula going forward with the franchise, which it absolutely needed.
