CLONES ONLY RUIN THE FRANCHISE!!!
Oh wait...
Honestly, I think some clones that make sense are kind've cool.
Fox and Falco for example. Obviously they would fight the same and have the same weapons since they were trained by the same academy and are part of the same crew.
Shit like that is really neat, it has like a Ryu/Ken thing goin' on.
Pikachu and Pichu... while I don't like Pichu.. it makes alot've sense. In basic terms for people who don't play Pokemon, a Pichu is a baby Pikachu.
The only clones I DIDN'T like were...
Falcon and Ganondorf... that made no goddamn sense at all. Clones like this should be fixed.
Dr.Mario.. I just didn't like him. It's like they were just reaching for a solid 24 characters and pulled this out their ass.
Clones have been part of fighting games forever, and alot've times it can be cool when it makes sense (Ryu/Ken both being trained by Gouken, Fox/Falco both being trained by the Cornerian Army).
