Widelands continues to grow as a great free and open source Settlers-like strategy game, with a brand new holiday release out now. It's fun seeing projects like this continue on for so long, especially as I grew up playing the likes of The Settlers on the Amiga and later Settlers 2 on PC. Good times, absolute classics.

The game has singleplayer and multiplayer support, with the developers noting it was originally inspired by Settlers 2 but has "significantly more variety and depth to it".
