I have never been happier with a crowdfunded project I've backed. The core gameplay loop is intuitive and interesting and makes the scenario - essentially moving through a tunnel - feel open-ended and replayable. These components can certainly be ported to other Mothership scenarios or sci-fi horror games.
Thousand Empty Light would be open to a number of different solo play styles, whether you want a single-session playthrough or to spend time further developing and exploring through journaling or recording audio reports in the log. This would also work for GM-less cooperative play.
The accompanying soundtrack is great. The easter eggs/ciphers are a beautiful and thematically appropriate touch as well. While I am sure the physical copies are going to be lovely, it made sense to me to print this on the photocopier at work. Absolutely pulls off the corporate training manual thing.
