A golden classic, man the hours I put into the game. Ubisoft would like to celebrate with you the 20th anniversary of the Anno series and therefore gives away Anno 1602 until December 23rd.

The game was released in 1998 and is thus, as Ubisoft describes it, still known to Windows 95 users - nevertheless, the classic can also be played by players from the 21st century, a trip back in time. 

The game will be available free up-to December 17 at 18:00 until December 23 at 24:00 (local time). Anno 1602 can be reached either directly via Uplay or via the Uplay website. In Uplay there is the item "ANNO 1602 Giveaway!" In the upper menu to the right of the "Store", then you can add the game to your library. 

So you need, whether through Uplay or the website, a Ubisoft account. Here is the link to the Ubi Store.
