My younger kid has been spending the past few weeks flying through the #Kirby platformer games, mostly in reverse order. They started with Kirby's Epic Yarn (#Wii), jumped to Kirby: Planet Robobot, then Kirby: Triple Deluxe (#3DS), and now are persevering through Kirby's Return to Dreamland (Wii again).
Kirby's Epic Yarn being the exception, I find the Kirby games became increasingly beginner-friendly as time went on. They never stopped being fun for experienced players, though. Neat trick.
