I’m planning a weekend away with 4 chums who are non wargames (well one is an ex wargamer) but we share an interest in ancient history, and a couple of them have suggested a wargames theme to the weekend (hooray!) along with perhaps a bit of walking in the countryside and probably a few beers each evening. So I am seeking suggestions for wargames that could be played on a standard dining room table without the need for any (or many) figures.
Command and colours springs to mind, but what other games like this would be easy to learn fun to play, and perhaps take 60-90 minutes per game?
