Not at all. You've just taken an extremely narrow viewpoint that I'm illustrating hardly matters in a slightly broader context. You can subvert the challenge in both games easily enough if one is so inclined, though I disagree using the cape in that way is as easy or obvious as you seem to think. But even if it were, it doesn't take much restraint to avoid abusing it.
My point was it's a game that similarly provides a different toolset to moderate difficulty at the user's discretion. If you prefer we stick to Mario, NSMBW had an option in which it plays the game for you. 3D Land would give you a power-up that made you invincible for the level's duration. Are those not essentially the same "problem"?
It's not a matter of caring, it's a matter of fact. If you don't like playing a game a certain way, then perhaps you shouldn't play it in that way?
No, you're really not doing anything except arguing that the ways in which developers design tools to be used in a game world doesn't matter, which, fine if you feel that way, but it's a silly, silly POV to me.
As for your arguments about NSMBWii and 3DW, these tools are at least meant for accessibility purposes, though I do think that they trivialize the platforming - how could they not, after all? I don't believe that the cape is meant to make the game accessible - in fact, the cape bounce is fairly easy to pick up, but might not be so easy to do for very young children or people with physical issues that make timing the d-pad push a challenge. Honestly, your comparison here makes me more critical of the cape bounce's designed use and not less critical; at least the "play the level/part of the level for you" tool is meant to clearly serve a group of gamers who might legitimately need the extra help for physical reasons. You can't even say that much about the cape's implementation in SMW.
In any case, your concept of the word "fact" is strange. You've given me your opinion that you don't believe it fair for me to judge a game by the way in which the developer develops tools to use within the game, which I think is dubious, but whatever, we're all different. However, if you think that this is a fact, you should probably hit the dictionary and learn what words mean.
Finally, I like SMW, and I enjoyed 96-starring it over the weekend, so I'm not sure where your idea that I don't "like" playing SMW in any particular way comes in. I'm just saying that, wow, the cape bounce makes a fair amount of the platforming totally unnecessary, which, you know, is an actual fact.
