A sword of fire is not unique? If Roy is included he will be tweaked as much as Falco and Ganondorf. Then the fire will truly be unique. Unless we have Takamaru.
We CAN'T SAY how unique Chrom will be since we don't know how he plays.
Judging by the way Sakurai treats characters in his resume, we can infer he would be a semi-clone of Marth. Unless of course you don't want to use any basis and just say "I have faith Sakurai will make him unique regardless."
That being said Chrom DOES warrant an inclusion based on the success of his game.
Soccer eye? Is zat you?
Characters like Villager aren't really all-stars per se, but they represent an important game so basically they are the incarnation of said game in Smash Bros.
That's a good basis for characters being imlemented because of games. But, there is a flaw with this. Chrom is from a series of 13 games of which he only appears once. Villager is from a series of 4 games ( I think ) in which he appears in all of them. Wii Fit Trainer is from a series of 2 games in which she appears in all of them.
I think it's more so that a
franchise can warrant an inclusion of a character. Not a particular installment from that franchise.
Awakening SAVED THE FRANCHISE so I think it would be ridiculous not to represent it in Smash Bros.
I really get tired of people using what THEY see as a warrant or merit to justify
Sakurai seeing something as a warrant or merit. People being like "Oh, well Krystal's most popular appearance features her staff, so WE don't see why it wouldn't make sense to implement it." or "Well, if it weren't for Ghiriham, the other stories wouldn't have happened so he should be in!"
Don't just use what YOU or your fellow Smash fans see as reasons why THEY think someone should be included as your basis for adding a character. Because for all you know, Sakurai probably thinks that's complete bull ****.
If I want to go around saying that Sakurai will look for another F-Zero character because he thinks that it should get another representative I will use a basis for declaring this a character merit. Like that Sakurai thought Metroid should have another representative.
I'm not going to use my own bias views on why
I personally think a character should be added. I will use what has gotten other characters included in the past.
I could go around saying that I think it would be ridiculous to not add Skull Kid because Majora's Mask is one of the most talked about games in the series. But, being the most talked about game in the series has never even been suggested as a reason for including a character. Nor has "saving" a series regardless of your potential and importance to it.
If it was like EarthBound, a relatively obscure and small series that didn't actually have several other protagonists to choose from than you might be getting something. But, adding a character just because his installment was more well received than than the last couple ones is completely asinine. And I don't know why people are running around going "Oh, he saved the series!". From what!? Wasn't the installment before it 3 years before it? What was endangering it???
