The Generically-Useful Naval Force Interaction Rules (Easy) is a naval war game for people who like their games simple, or for people who want to fight big naval battles without getting bogged down in details. The era is the first half of the 20th century.GUNFIR(E) assumes you have some of my All the Ships counters, or a set of 1:6000 naval miniatures. You'll also need maps, as described under 'Setting Up a Battle.' All you provide is one 20-sided and two 6-sided dice. - BoardGameGeek
