I have played Subterfuge 6 times in the last 3 months and really enjoyed the banter and strategy that went into each game. However I am reluctant to start another game. The reason, this game is exhausting! The number of times I found myself obsessing over orders at 3am was really disconcerting.
If you play to win you are basically committing yourself to on call status 24hrs a day for 1 to 2 weeks. For people who work/socialize/sleep this commitment is unsustainable in the long term. What I propose is an option during setup to pause the game at specified intervals; essentially a daily timeout. For example if you included an 8 hour pause per day, players could get some needed downtime, sleep, talk to the spouse, etc... then return to the game action feeling refreshed.
I don't believe a game pause would be difficult to implement programmatically, and it would help prevent burnout in the player community. Now I've heard the developers are no longer working on the game, but it doesn't hurt to put it out there.
