I meant to tell you guys about this a couple of weeks ago but life got in the way, so please forgive the fact that there's only a week left in the campaign!
Disclaimer: The writers Josh and Becky are RL friends of mine but I wouldn't spam the forum unless I thought the game was really good. I've playtested it and the game's really good! My storytelling ability isn't the best and I'm very out of practice at improv, but as a group we created stories that were genuinely creepy and disturbing and interesting, and I really enjoyed the process.
My favourite part is that at the end of every scene each player secretly writes down what they think is going on, based on the clues that have been given in the game (by the players). It's really cool trying to tie new clues into your concept of what the story is about, or realising that the latest clue gives you an entirely new idea for what's going on - this mechanic means that whenever someone introduces a clue it kind of fits without you having to have any kind of discussion about what the plot is, or is going to be. That's really neat, and very hard for me to explain!
There are bare-bones rules available to download (link on the KS page) if you want to try it out. They've very close to reaching the last stretch goal - they already have some awesome people commissioned to write essays and modules including Jason Morningstar (of Fiasco fame), who loves the game.
