Having instigated this, I feel responsible - and I certainly don't want blood on my hands if the game slots vanish entirely again =( However, I've not really got any ideas. Except, well... I've seen an online game called NationStates where one runs a country via its inner workings. So I wondered if perhaps we could invent the continent of Morningtonia, each stake a claim to some land and then see how our national/international diplomacy skills are... and hope that the answer to the question "When does the game end?" isn't necessarily "NUCLEAR WAR!"
I dont' think MC itself works very well here. It really has to be played live so that the players can display all the mock-gravity and in-depth knowledge of arcane rules that this involves. It's a performance, really, and needs rather good actors.
Then maybe a game of 'Dress Rehearsal Mornington Crescent' will show what sheer hard work has to go into putting on a slick performance in the Game itself? I'm thinking this might give us an insight into the director's final, fraught instructions, the referee's frantic consultations with the rule book(s) and the performers' last-minute nerves showing through.
