This is super cool. It makes me think of the current popular clone of the video game Lethal Company which is called Content Warning, about vloggers trying to get footage of monsters.
In 1958, Disney made a documentary called White Wilderness where they 'documented' Lemmings following eachother off cliffs, becoming a widespread fact. This was proved to be untrue decades later; The documentary crew herded them off the cliffs to their deaths for footage. In 2003, Timothy Treadwell and his partner were killed and ate by a brown bear after living with them for years. The 2005 documentary Grizzly Man by Werner Herzog uses a lot of his own amateur footage documenting his delusion, partial success and ultimate failure that he could live among grizzly bears. These are fantastic sources to derive characters from for this game.
Honestly the idea of using this to run a black comedy sci-fi horror documentary to basically do Blair witch in space is so appealing to me. The only thing I'd alter is that I'd make it a livestream with viewers, donators and sponsors who respond well to the gruesome and macarbe moments. Not just do I think that's fun but also by being a livestream, the players would likely take a much better hand at pacing and seeking the fun than in typical games, where the GM must herd them to these moments, as the players believe they win by getting a lot of donators.
