There is a version of Memoir '44 developed by Days of Wonder that can be played on PC and that has also been published on Steam. This is a pay-to-play game that comes with a few tokens that allow you to try out the game after downloading it.
After you spend all of your tokens playing, you need to buy a pack of tokens that cost real money. This has resulted in some mixed feelings in the reviews, with only 50% of the players giving it a positive note after playing (stats for the past 30 days).
I have not tried it, but it seems to be possible to play scenarios against a CPU, but I’m not sure if that spends your tokens. I cannot try it since I’m using Mac OS.
Have you tried it? What did you think? How does it compare against other ways of playing Memoir '44 online with other players (e.g. Vassal mod)?
