Ha, indeed, yes, maybe.....
I now see in the demo we have :
ORDERS : Immediate or delayed
DELAY : Limited or Historical
From my tinkering around I would say the "historical" is very very tough, on "limited" I find it far more playable, there are still delays but they appear to be a lot more reasonable than when set to historical.......I would say historical would be excellent for a campaign, but not so good for a face to face battle where the action is happening all in one day.
I believe with ORDERS at delayed, and DELAY at limited, we have a very nice "playable" setting but of course everyone will prefer their own combination of these things.
