There would need to be somekind of list that would work with "first comer first served" mentality. I would be more worried about those turns/nations that nobody wants to play. Stalling is not an option.
Those tourist games would be great. Think about championship tournament where players would go 1on1 and the whole community would watch. Think about players like Baalz, Wraithlord or mr. Parker going at each other with full speed
All the masters at action... Now that would be something to see

And to speculate in the forums
