Had a chance to play this scenario last night. Really enjoyed it. Well designed. The way you have the initial set up really creates some tough decisions early on for both sides, which created a good amount of tension right from the beginning. The mass of Ostrogoths in the center vs the potential flanking attack of the Romans. The Ostrogoths will be very tempted (depending on cards of course) to attack hard in the middle but this could be a real trap. I also thought the use of the terrain was well done, it presents more decisions early on.
My play resulted in an Ostrogoth victory 6-3, but it was close. In fact total casualties were Byzantines 31, Ostrogoths 32. So the Ostrogoths won, but at a big price.
The Ostrogoths decide to attack the Roman Flanks with their cavalry, hoping to cover/protect an assault in the center by their main forces
The Romans respond dividing their main line in the center to counter the flank assault and successfully repel the Ostrogoth flank attack
Having successfully repelled the Ostrogothic flank attack, the Roman decide to press the attack on each flank
The Ostrogoths reform on the Roman left flank and counter with some success as both side temporarily pull back due to heavy casualties
The Ostrogoths survive a heavy ranged attack by the Romans and prepare for their final assault
The Battle ends in an 6-3 Ostrogoth victory after a successful assault by Cavalry and Warriors on the Roman right
