Why would you play on 0.0 even if it's possible to beat challenges at that difficulty... it's be a super bore.
I'll probably go back through again. I just wanted to get the challenge done. It's a completionist sort of thing.
But what irks me is that you're blaming the game for your choice. The word is "could", but not "should". Unless they forced you to play at a lower difficulty, I don't see a justification to hate the game because of a decision you, not the game, made. With that logic, one should also hate the fact that you can unlock characters through SDing or putting the AI at 300%.
I do not hate the game.
It should, because all games should be ordered to the principles of good game design.
Now, it occurs that the intermediate goal of a game is to convey the means by which one may accomplish the ultimate goal, or set about applying prior logic to new circumstances to develop new skills.
Therefore, it is within the purview of game design to be as openly consistent as possible, to reduce potential frustration or confusion. Smash is not a type of game that ought hide the means to its ends. Insofar as it fails at that, Sakurai and or the people who have developed this portion have failed this principle. Of course, this is not to say there are not unforseen consequences, but it is clear that something of the nature which this thread is dedicated to would most likely be an intentional design.
A hide-and-seek game cannot be taken as a violation of this principle, since the clear and stated ultimate goal is to keep things hidden and force the player to think in a broader context. Ultimately, it is still solvable.
It seems that the ultimate goal of Smash is not to hide or focus on intrigue. Therefore, one should not be expected to know things which they have no way of knowing until it is done. We know from previous Smash games that the natural progression of things will usually take us to unlock new features, and that ending matches is one such criterion. Therefore, it is clever utilization of given conditions which leads us to SD to get the new characters, with little uncertainty.
One would have no prior way of knowing that he had to complete it at a certain difficulty level, because it openly contradicts the implication of the challenge 'clear classic with all fighters'. For clearing simply means that. If no condition of difficulty is made, then difficulty seems just as inconsequential as whether a cucco appears on each stage. One can easily see how ridiculous the latter condition is.
Make no mistake, I pass no moral judgement, I am passing a 'game design' judgement.
Fortunately, I was just being a doofus.
