Lords & Servants
A skirmish set for the medieval period from the creators of Impetus
L&S is a skirmish set that allows you to play games with few figures, but also engagements with 70 to 80 miniatures per side (you can choose among three formats: Small, Medium and Large). It covers from the Dark Age to the end of the XV Century (but they include rules for artillery).
The rules are based on the Smooth & Rifled system, but with more emphasis on melee. Miniatures can act both as single figures and in groups. A points system allows you to create and customize your force. The set includes lists to play the Feudal age, Mongols, and Wars of the Roses. Lists, of course, can be used as a guide to develop other forces. Anyway, more free official supplements with lists will follow.
The set is available as a PDF through Wargame Vault, and in around one week also from the Dadi & Piombo website. In both cases, you will get, for free, future digital versions of the rules.
