The trend among fighting games to include a character who is a near carbon-copy of another character rather than use that roster spot for a unique and interesting character.
For instance, SSBB. I can forgive Wolf and Luigi, as they were differentiated from Fox and Mario enough to be similar but separate. Then there is Toon Link, who is essentially Link but smaller and with a different model. The differences between him and Link are superficial at best. The same goes for Gannondorf, who is a slower Captain Falcon.
The problem is that they could have easily cut out Toon Link for a more interesting character, and Gannondorf has a myriad of fighting styles from the other Zelda games he could have used! But Nintendo succeeded in avoiding ALL OF THEM.
Then the fact that in MVC3 they could have cut out Akuma, who is mostly identical to Ryu, and used Frank West!
