Looks like this is an hour early. Ho well. Anyways, I haven't played any Kirby game... Ever, I think the closest thing I've got to Kirby is super smash bro's so I don't know too much of the mythos or of the gameplay to really shake my hands in the air.
I do know that my niece who's 4 can play the original Sonic the hedgehog without too much trouble until she gets to some of the later levels and thats only around 400msp as opposed to the price of a full retail game so I often put that on for her if she feels like gaming. So I don't think theres much need for this. Also, yeah, I can't think of any games from my childhood that pussy footed me around. Though I grew up on games like Sonic, Mario, Rayman and such... I do remember a Smurfs game that came out once and I was a little bored at the fact that it was literally impossible to die and that was on the PSone so I'd have been around 6 or 7.
So yeah, games that are this easy don't really present much of a challenge to kids. However maybe thats a good, thing... I don't know, I haven't played it.
