(Straying a bit off-topic, I fear, but I’m compelled to toss in my two cents…)
Relatively speaking, perhaps, compared to still-merchandised icons like Cinderella and newer main characters like Luca and Alberto. While they both have, at best, a cult following, they’re less obscure than several characters already in the game, such as Mr. Big & Koslov or the Rocketeer.
Neither Goofy nor Powerline punch enemies, either. IMHO, it wouldn’t be any harder to come up with a usable skillset for Cinderella than it would be for, say, Joe Gardner.
An adaptation can certainly be radically different from the source material and still be good, true. Who Framed Roger Rabbit and (from a different studio) The Secret of NIMH take far more liberties with the original books than The Black Cauldron does, but did so in ways that play to film’s strengths and that served the filmmakers’ themes. And The Fox and the Hound makes those adaptations look like sterling examples of fidelity to the source material.
I wouldn’t want a steady stream of one-scene wonders, but Finnick has been one of my in-game favorites since day 1, so I wouldn’t want to forbid characters based on limited screen time either.
I would seriously love it if that’s what the friendship campaign turned out to be.
