I think after having gotten to a certain point in this game, I have come to realize I cannot move units larger than the size of a regiment in TC mode by way of courier system across the map, actually I cannot move units in TC mode at all larger than a Reg. For example in scenario # 7, cannot get my units to flank Round Top because the units all go directly north to face the enemy. If I try and TC an entire brigade, they will not respond to orders unless they are stationary. For example, I TC the brigade CO, now all his reg's are TC'd. I order them to form a column and go here or there, "have your unit go to this map point" and only the leader goes.
This makes the game not really worth playing after a certain point. Who wants to have to order each Reg to do something. No one has been able to explain in plain English how to move entire brigades or Divs in TC mode which leads me to believe it can only occur in some arcane mod fashion. Really poor design IMHO and completely not dealt with in the manual.
And another really disappointing feature that can somewhat be remedied by using custom option is that on the grog diff mode, the map does not update with the accumulation of intelligence. Why would a map be completely blank in Grog mode? Certainly the CO would start out knowing where his subordinates are! This is absurd. Then, when the enemy is sighted the CO would fill in his map accordingly. But this does not happen in Grog mode. How absurd is that?
I cannot recommend this game for these reasons!
