Andy Watkins offers a set of skirmish rules for the Wars of the Roses. Watkins writes:
25mm Skirmish wargaming with Wars of the Roses figures was one of the first Skirmish games I ever played about 20 years ago. To be honest I haven’t played much for quite a while. The rules I used were a bit cumbersome, I’ve upgraded now to a home grown set that owe more to my Pirate rules than anything else. Though there is still a touch of influence from Retinue, the best of the commercial Wars Of The Roses rules.
