This is the online implementation of Days of Wonder's Memoir '44 boardgame, downloadable from the Memoir '44 Online site. Memoir works on virtually all computers produced within the last six years and requires a Java environment to run. DoW provides installers for Windows, Macintosh and Linux.
To play Memoir '44 Online you need to have either an Days of Wonder account or a Steam account. Then you can enroll for M44 Online and receive 50 gold ingots (what are gold ingots?) to try the game out (Steam users will be given the same 50 free initial ingots). One play costs between 2 and 3 ingots. In addition there is an Expert mode which will allow you to play scenarios designed with the Memoir '44 Scenario Editor (Expert mode requires the purchase of a Captain or Major ingot pack).
