Exactly
But you try to avoid that when you are playing with newbies.
I agree it's a good use of time and you can plan things out more, but that is precisely why I personally don't enjoy having them. It allows certain information that can be attributed to rumors, buying information and other sorts of activites by a national spy ring, but I prefer to have some sort of way to invest/direct that sort of thing (I'm a glutton for control), so turning it off and letting the spying and in turn the patrolling being the Cloak and Dagger of the game, instead of a game mechanic.
I usually don't have people miss turns on my servers. My recent game here at Shrapnel has been the only one where I've been more harsh on it, simply because there have been a rash of games that didn't get off the ground here for newbies.
Just different ways of looking at it, I suppose.
