The dem of the new (semi) historical 4X game by Paradox games is available for 1 week longer, until February 19.
The demo will be single player, and you will be able to play at maximum 60 turns up until the 3rd age. This allows you to explore the age system of Millennia, which allows you get into alternative history, giving overall more interesting options for the game.
You can discuss the demo with us here, and also read more info at ParadoxPlaza.
