Blah blah blah, is right. What a mess of chat log dialogue! Though, I guess that's something to be expected, right? Three pages of back-and-forth rambling makes me really wish the two guys to have put their passionate speech into an effective debate format. I guess time is always an issue, eh?
Anyway, on to the subject at hand:
Mr. Gaimin's zeal to his claim that the C-stick is a detriment to the game is a tiny bit disturbing for me. Seeing such care for a stance on an aspect of a game is always an interesting sight for me.
I think the best analogy to the C-stick was if there was just a single button press to preform one of the more basic Street Fighter II specials (Hadoken or Hurrican Kick). That was mentioned in the chat, but replaced by more unwieldy analogies. That best sums up Gaimin's arguement where the depth of a "real" smash is concerned: There should be a sequence that one can mess up when one is trying to preform something powerful. A SF2 player has to worry a bit to fire off a hadoken at exactly the right time the player wants to, and the 236+punch adds difficulty to that timing. In Smash example with the rushing Shiek, the defending player who needs an instant Smash would worry about not holding down the A button during the smash input sequence. The Hadoken button and the C-Stick would be eliminating an element of worry and the need for this specific finesse.
My view on this is that the C-stick is a welcome ease-of-usage option in a game that is all about accessibility. That accessibility extends to the controller with the philosophy to make it easy as possible for anyone to do something awesome and precise. I don't think having precise control (e.g. using the directional aerial attacks while mantaining a certain direction) should be made difficult at all in Smash. Anything to break, or at least soften, the control barrier between player and avatar is okay for Smash, in my book. There are games where the winning-or-losing timing is between player and a string of controller inputs. I don't think Smash should be one of those games, and Smash should be as far away from such games as it can be.
