I agree. The Command Deck contains a number of cards which are useful only for infantry. This means that a cavalry only army can suffer an initial phase of semi-paralysis, in which only a single unit can be moved. Some bad luck in drawing and the paralysis can actually last several turns. Thus, in my experience, a Roman victory at Carrae or Nisibis is well possible if the Roman player is able to read the situation and press the opponent. But then maybe the opponent is bluffing and waiting for the Roman to expose his troops... the beauty of the C&C system.
Edessa, in addition, suffers, or enjoys, the random nature of Elephants warfare. In this scenario the Elephants are more powerful than normal, but they can still fail miserably and at that point it's difficult for the Persian to bring a victory home.
Misiche is the only scenario that features some significant terrain. It's a nice scenario with an unexpected, for me, tactical twist: the battle is won or lost on the Roman right flank, despite the fact that the strongest units are on the other flank. It took me a couple of games to realize this fact. Let me laugh at all those who consider C&C:Ancients a shallow game! (I know, maybe it's my brain that is shallow!)
Edit: I added my consideration on Misiche because I realized all games for the tournement have been already played.
Edit2: Grammar, please!
