Iron Storm: The First World War, 1914-1918

From BoardGameGeek:

Iron Storm is a two-player strategic wargame that allows you to recreate the entire First World War in a single afternoon. The game uses an innovative card engine system where each player uses their entire hand in one go, to activate armies, resolve operations, and support battles with combat cards. It also simulates human and economic attrition during the course of the war by gradually adding cards to each deck that will have limited use in the hand and take additional effort to remove. —description from the publisher
