The one that stands out most right now is that Kassil's Saturday night Eclipse Phase game was epic. We ended up with 10 people, which even in a horror scenario, actually made it feasible to split up.
We were all living and working on the edge of Sol system, in a little space station attached to a massive radio antenna array. And now we woke up in sickbay: in our backup bodies, with a 2-week hole in our memory (since we backed ourselves up prior to going out to assist a ship which had been experiencing trouble with its fusion plant), with the wifi that normally connects to our brains being actively jammed, and with only a recorded message from the station AI asking us to show up at the server room and implement repairs ASAP.
As soon as we left sickbay we found that just about all of the station maintenance bots were doing various things to try to kill us, personally.
Then it got worse! :D
