The first game, Kirby's Dream Land will forever hold a place in my heart that not many games can. It's the sort of fun you just can't describe. Beating Wispy Woods with just air shots, flying over Dedede's head... That said, Kirby's Adventure is my favorite, even though they officially changed him from white to pink at that point. The abilities in that game are great, and the levels never got boring for me. I think I held on to Suplex longer than is healthy. Nothing beats tossing your foes around!
