Watched my son (Daniel, Britons) play this yesterday. He and his opponent (Peter, Romans) picked it because of the unusual nature of the British forces.
The early battle saw the British chariots thrashing the Roman light infantry. Pete got a bit of a rush of blood and lost a medium calvalry unit in a premature attack.
The PBI (poor bloody infantry) of the Romans had to slog forward, with the Britons evading every attack they could, but being pushed back towards the board edge.
The game changed when Ceasar, with a medium infantry unit, seperated from the battle line. Three chariot units attacked it, hoping to wipe out Ceasar. This was not to be. Ceasar urged his men forward, and with the benefit of an additional die to battle back attacks, wiped out the the chariots, taking loses as he did so, but coming out victorious.
Definately a game of two halves. The Romans just have to suck up the damage as his infantry advance, but then go in for the kill when the Chariots can evade no further.
The British chariots slammed full-steam into the Romans. At first it looked like the British were doomed. The Romans hit back cracking most of the British units. However, after learning how to do hit and run tatics, the British did better. The Romans had no line command or leadership cards and could never move forward in order. The Romans charged their calvary too soon, losing them. The Brits won 6/5 in a turn around game.
In this rematch, I was now the Brits. I got a mounted charge early in the game (the whole game was just 7 turns) and hit the Roman left. I was able to do some fair damage though lost a unit of chariot. However, the Roman general on that side had to retreat to a calvary unit. One my next turn I was able to surround him and crush his unit, and him. I was then up 4/2. On my next turn I hit the Roman right and was able to pick off an archer and one more in the the Roman left. The game ended 6/2, making up my lost as Caesar several days before.
