Undoubtedly the peak of the Kirby series. The "Six Games in One" structure was really an oddball but still very smart way of introducing a ton of creative variety and fun ideas into the game without having to worry about making it all fit together. Combine that with superb technical polish, and combat and platforming so satisfying and engaging that it formed the basis for the Smash Bros series, and you got one of the absolute stone-cold classics of the 16-bit era.
