LIke people have said, i don't mind clones, or luigifyed versions of characters if there from the same series. Fox, Falco, Wolf all having blastersd and reflectors makes sence, they are from a shooting game essencially, what else would you propose to give to them, snipers and rocket launchers, hardly.
It is when they clone characters that have no relevence to each other that drives me nuts, the C.falcon Ganon one being the worst. Many expected Ganon to be de-cloned in this game because there was so much you could do with him, i.e. sword and electric-magic attacks. There is no reason to cross-clone characters. Luigi-mario makes sence, Link-toon link makes sence considering in all zelda games you do the same basic sword maneuvers, pichu-pikachu made sence, Doc-Mario-obviously did too.
Chrono i've argued with you in the past, but what you say here is very intellegent, clones do help bolster a roster, think of it if Brawl had no clones, we probably wouldn't have Wolf, Toon Link, Falco, or Ganon. And i like some selections you made for the next game. The Bowser Jr. one is good, same with Vaati and Zelda, aswell as the lucas-claus or ness-paula(this one especially because paula actually uses ness' moves). Good read, i look forward to reading your next post/edit.
