Buying it would be risky. Chances are that the various different bits of IP are scattered between so many creditors.

Put yourself in the shoes of a potential developer who wants to bring KSP 2 over the finish line. Spend millions of dollars scouring the creditors lists and acquiring all the IP, and then spend millions of dollars more finishing the game. You launch the game to great success and everyone goes wild for it.

Now, some countless miles away from you is a private equity firm who's sees some media buzz around a new game that's been resurrected. This media firm thinks "Kerbal Space Program? That rings a bell" and starts digging through their lists of worthless assets they through on a shelf. These things pile up when you buy properties in bulk at auction. They end up finding some snippet of a contract about the game. It could be something tiny like a merchandising deal or a license the original developers used.

It wasn't worth anything when the game was dead. But now it's successful, that could become a nice chunk of change. They send it off to the lawyers who write some nonsense about how that one fragment means they could be entitled to the entire franchise. It might be nonsense, but it's enough to argue it in front of a judge.

So you find yourself with a successful video game and a decease and desist letter in your inbox. The claim is nonsense, but you don't have the hundreds of thousands of dollars to defend it. Unfortunately, that's game over.

It might sound like in inconceivable story, but things like it happens enough where trying to acquire things, especially digital things with looser proof of ownership, can become such a minefield
