Well... I feel like there are several problems with this one.
1. Was crystal chronicles popular enough to warrant this? It got enough press coverage, but I'm fairly sure it wasn't extraordinarily enjoyed by players. I know I wish I didn't spend my $50...
2. Not really a character, just a race. Honestly, if we were going for final fantasy races, I would much prefer one that's been in more than one game. Such as moogles. So, it seems to me that if smash bros. got some final fantasy characters, the Crystal Chronicle races wouldn't be that high in consideration.
It'd make for an interesting set of clones, though- taking the crystal chronicle races. And some interesting costumes. The different race attributes are practically begging to be cloned, and I wouldn't mind that since it'd be fairly true to the game, and they would be able ot change around a few attacks based on the individual races' weapons.
Someone ought to make a movelist... I never used the yukes so I don't think I should.
