Fantasy/ECW, based on the Lord Kalvin of Otherwhen
science-fiction novel by H. Beam Piper. It was designed for 25mm miniatures and included a list of
manufacturers with notes as to which sets are most appropriate. It even
had a painting guide for the Armies of Hostigos, Nostor, and ?? (can't
remember the other two countries). The notes say you can use it for the
English Civil War,
but I don't think I would ... the rules are ok, but there are better
sets out for ECW.
