I have been looking for a good set of Dark Ages rules for some time. Whilst I like Saga it is really a two player game and so doesn't provide a complete answer. So when I had the opportunity to playtest Dux Britanniarum, the Dark Ages rules under development by the Too Fat Lardies I jumped at the chance.
The core rules are actually pretty well developed but are intended to work within a campaign system which is still being worked on. They are intended to cover the period following the departure of the Romans from Britain and the arrival of the Saxons.
I set up a game with the suggested Romano-British and Saxon warbands and here's what happened.
The locals had spotted the Saxons approaching and had decided to meet them in the open ground before their settlement. The Saxons gained the upper hand straight away and decided consult the omens which showed they were blessed. The British leader decided to inspire his men and made a rousing speech.
On the other flank the British swept aside the Saxon missile troops and charged the small shield wall, killing several men and driving it from the higher ground. Meanwhile, the main Saxon force, realising they had to act of have their flank exposed charged the British shield wall once again and were repulsed once again. With the Saxons outflanked they withdrew from the field.
