The rules are well laid out, and the index and larger than normal font makes a big difference in navigating ones way through them. The mechanisms are easy to follow, with a minimum of charts and tables. They certainly don’t appear to be especially complex. My earlier comment notwithstanding the booklet is well supplied with nice colour photos of figures in action, and illustrating elements of the rules.
For me the scenarios included towards the end are of particular interest. I don’t own an ECW collection but do have other 17th century armies so I am keen to give them a try to see how well they provide a fast and simple game with the correct 17thC feel about them. So, well worth getting hold of. Recommended.
