It depends on how much of that hard-'earned' money Inno wants to spend playing Whack-a-Mole with the people who take up the mantle. If I have this correct, as long as the suit is filed correctly, it can reach a courtroom. At that point whether it's justified is up to the court. If the 'new' development team doesn't respond, Inno would win by default. Again, that's my understanding of the outline of the process, not the legal merit.
The whole thing could devolve into an 'in forma pauperis'/'pro se' battle, which I would need popcorn for.
But yes, if financial backing dies off because a person or group of people hijack the game's development and produce it for free, Inno could sue for damages. This is her job after all, however poorly she manages it. She couldn't do shit about competition with new/different code, though, unless she wants to risk a countersuit via antitrust law.
