I personally feel equating Star Wars FCs to comic book FCs in a MU* sense is sort of unfair.
The reason being that the vast majority of comic book games do a 'Year One' style for FCs. Meaning you choose what history to build for them. Which comic era or even your own take on their background. Add that to the fact that there are so many more of them (with the size of the MU* community nowadays, I think it'd be impossible to run out of Marvel FCs).
But with Star Wars, you have a fairly small pool of FCs unless you go into people apping random Cantina patrons and the like. And a lot of us have been there. On games with FCs. Where plot crops up and the whole scene centers on the FCs in the plot, treating OCs as if they're just there to ooh and ahh at the FCs. Or the majority of FCs sit in their rooms and idle.
Will that happen here? Maybe not. But I've been in the shoes of the OC-player because I'm not cool or Staff-friendly enough to play an FC, struggling to ever feel involved and being told that to 'keep with the spirit of the game' everything must filter through the FCs. Being told 'Your character is special because they get to witness these major figures do their thing!'
That's like telling the kid who sat on the bench the entire season that they're special because they're part of the team.
Who knows. Maybe in six months or so, this game will be great and someone I trust will come along and tell me 'No, seriously, people who aren't FCs and aren't bffs with Staff DO get to be involved!' and I'll happen on by. But I just don't have the energy anymore to put a lot of time and love into an app only to sit on the fringes at every turn.
