Right, well, I'm away for a couple of days now... I'll have my phone, and might even have free wifi in the hotel, but I can't guarantee long posts...
So, I will say this now. If you want me to run this - it was my idea after all - I will. But not as any sort of active GM.
BUT: If I'm running it, then it's by my rules. That means we have a dormitory. Sorry, but that is the only way I can see it working. I've started a lot of group games over the years and NEVER had one reach that magic 1000 IC post count that makes it a large game. So I'm pretty cynical about that. The only game I ran that came close was the Mars Colony, and that hit 500 before it died.
This game I see as dying out somewhere about the75-100 post mark if that - there is no story and not many people, and I can see the whole thing just folding in on itself after a couple of initial sex scenes. Yes, I'm being negative, because I want everyone to know why I don't want to run the damn game...
Anyway, point is, I have a lot of experience with killing games off. top causes are:
1) A small group (five or six) in a story-based game and one critical player drops out.
2) Everyone pairs up and has their little sex scene and then loose interest.
3) GM looses interest
4) The game goes in a different direction to that which people were expecting
5) Everyone is waiting for their chance to post, they get bored with waiting and loose interest.
There are other causes, but those are the ones I can think of.
If we go down the "One-per-cell" route we have Cause 5. Cause 2 will happen if we go down the two-per-cell route.
By the way, the suggestion that people get random cell-mates sounds good, but it assumes that the game lasts longer that one day of game-time, which I can assure you it won't. So there is in effect no difference between that and just having two people per cell.
Bama, I'm sure that Pam can do interesting things with handcuffs and iron bedsteads? And there would, of course, be an "isolation" wing, where you get put if you are really bad - but remember that if you're in there, you don't get let out when everyone else does. "The Block" or "The Cooler", is solitary confinement, and that means you are in there alone except when one of the guards comes visiting...
