That’s certainly a lot better than what was on the blurb, and I fully appreciate both the efforts taken and the artistic aims of the game (and again, I’m glad that people are trying to do these sorts of games). At the same time, its still not entirely clear about what the players are in for (other than an intense psychological experience - which is advertising, not a warning - which will involve psychological and emotional abuse - which is a tad vague).
I also understand the need to avoid spoilers, but if its something you’d learn in the first few minutes of a three-hour larp, its not a spoiler. Unless there was a specific reason for secrecy, I don’t think it would have hurt to say upfront something like
“This game is inspired by the Stanford Prison Experiment (link). It will involve themes of power, authority, sadism and helplessness, as well as finding out how people react when placed in positions of authority over others. You may learn unpleasant things about yourself as a result.” (plus existing warnings about acting out physical violence, and on psychological and emotional abuse).
That way, people can find out what they’re in for before they’ve made a commitment to play.
(Personally, I was put off by the blurb, as not offering enough information to judge what the game was about and whether I wanted to play it. Plus, I was GMing that night. From the discusisons I’ve had with participants since, I’d likely play it if it was re-run).
