Windows: To celebrate the 20th anniversary of the launch of Anno 1602—the very first game in the celebrated “Anno” strategy series (which has since stretched all the way to Anno 2205)—publisher Ubisoft is giving away the game for free.
The catch? It’s a Windows-only download, which Ubisoft even teases in its description of the promotion: “If you remember what Windows 95 looked like or if you were born in the 21st century take the time to discover or replay this classic for free.”
You also only have until tomorrow—Saturday, December 22—to grab the game. Otherwise, you’ll have to throw down $10 to relive the nostalgia of building pixilated colonies and fighting off rivals in the 17th century.
If this sounds like fun, but you hate the idea of having to learn the intricacies of a new, complicated strategy game, don’t worry. Since Anno 1602 has been out for more than two decades, plenty of players have already created some excellent walkthrough videos you can watch to ensure your first few attempts at building a new world don’t self-destruct:
