A few days ago I found that Matrix Games have released version 8.0 of Steel Panthers World at War, in my opinion one of the very best turn-based strategy war games ever made. It is based on the classic Steel Panthers series by SSI, which was taken over by Matrix Games and released as a free (!) game.
It has much improved graphics and game-play over the original games, as well as has a large user community of players that discuss tactics and help each other out with issues. I highly recommend trying out this game for other strategy interested people out there!
