Ur not alone when you say that it'd make you livid. It'd make me about three or four times as livid as you because I always blow literally everything out of proportion XD
As for the Ridley v.s. Olimar size thing, I think the reason that they have made Olimar as big as he is is due to balancing reasons. Seriously it'd be seriously f*cking unbalanced if they made Olimar smaller than a crouching Kirby (i.e. the shortest current character in the game) without him even crouching because he'd be virtually impossible to hit.
As for Ganon, literally the only reason that he was made a Cpt. Falcon clone in the first place was so that he could be grouped with the other Zelda characters on the melee character select screen. I mean, if they had made him an original moveset and grouped him with the rest of the Zelda characters, the pattern of the roster would be ruined. Take a look at the melee roster real quick:
Clones are all placed around the edge next to the characters they are clones of and Kirby is in the middle because its Sakurai. If they had done anything else with Ganondorf, the pattern would have been broken. Therefore, they chose a humanoid character which had a sense of power, cloned it and changed the fire effect to a darkness effect. From the perspective of the smash team at the time, it makes a lot of sense to make him a clone of Cpt. Falcon. It allows them to pair him with the rest of the Zelda series characters while also sticking with the pattern of the rest of the roster. It is most likely the reason they even bothered to include Young Link in the first place, so that Ganondorf could fit in as a clone while not being separated from the rest of the Zelda characters. Then, they come to balancing. Ganondorf was able to keep the attribute of being bigger than Link, and his melee model is approximately 1.3x bigger. While it is no 2x or 3x, it is still significantly bigger, which remains true to his character in OoT. They have done Ganondorf well, and he feels like his own character in consecutive versions. Done well.
Ridley would be really difficult to do (a 14 year old has done it for PM, but the Ridley in that is stupidly unbalanced), and I feel that Sakurai made the right decision. While it is true that it is impossible to make everyone happy, I feel Ridley would have a far larger ratio of unhappy people to happy people when it comes to his implementation, and I feel that Sakurai is right to be cautious with him.
I won't comment on anything else so that I don't encourage the tangent to keep going, but lets try to not get into arguments over this kind of stuff :]
