Two threads is double the fun,
but when you're trying to work on other things simultaneously it makes it so that it's all you can do to keep up with what is happening on the threads.
Basically after Day 2 I was only half-playing- I was keeping up with everything but no longer able to read carefully for suspicions or hints and no longer making charts etc. So while being dead was fun, I'm not certain it helped me play well if you follow (though the concrete knowledge sort of makes up for that in terms of providing guidance).
Anyway, fun game
Kuru and all the players. Well fought.
