Twice I've gamed in a launch control center, while on alert as part of my missile launch officer duties. We were down there in the capsule, monitoring the ICBMs in our flight, for 24 hours at a time, so there was plenty of free time needing to be filled. The first time, it was a solo adventure (one of those "magic viewer" deals with the red glasses, and you're running a sole PC and reading the DM stuff through the viewer when necessary). The other time was when my crew partner and I were sent to Vandenberg AFB for a test launch - we played Star Fleet Battles multiple times and he ran me through a Top Secret adventure.
