If you enjoy Kirby's games or have any interest in a very diverse and fun platformer title, this is the game for you.
A few years ago, I played Kirby Super Star with a close friend of mine. For five days straight. We played the hell out of this title and had an absolute blast. The game offers an updated port of the original Kirby's Adventure, as well as different titles that range from traditional fare (Dynablade), to more puzzle oriented titles (Great Cave Offensive).
I had a lot of fun with the title and recently rediscovered it on the Wii's Virtual Console. I really can't stress the need to play this game if you're at all interested in Kirby. It offers some of the tightest gameplay and variety of the entire series and is my personal favorite out of all the Kirby titles. At $8 you'd be hard pressed to turn down such a great deal. Go get it!
