It's a bit harder to reverse engineer a game from a video stream than from a binary+data dump ;) (of course an LLM can come up with a knock-off that roughly has the same theme of what it sees in the video-stream, but that would basically be "Italian Spiderman - the Game".

Sure, but the LLM can either 1. recreate the assets from the good old "view it from multiple angles" trick 2. exfil the running game from the servers :P
