I actually understand why they created the Vong. The Empire-as-antagonist shtick had grown very stale, and they wanted new enemies that would feel different and fresh.
Unfortunately, they felt too different, like they'd stumbled out of Star Trek or some really bad anime. It didn't help that the 'emo kid S&M faction' was supposed to be just a part of the race, but someone made an error and made it the entire species.
Then the whole 'immune to the Force' thing just felt like they were a broken answer to the corner that the writers had painted themselves into by making the Jedi into unstoppable ninja supeheroes who needed overkill gimmicks to challenge them.
I don't feel they were intrinsically a bad idea, but they were poorly handled.
And as the focus of the FFG games is supposed to be the original movies, I think there's pretty much zero chance of this game including them.
