The Battle for Wesnoth is a free turn-based strategy game licensed under the GPL. After over one year of constant development, a new stable version, 1.6, was released on March 22, 2009, featuring many graphics and gameplay improvements. To count just a few, you can now log into the multiplayer server using the username and password from the Wesnoth forums; the game includes new graphics for terrain and units (including several new portraits); a new campaign, called ‘The Legend of Wesmere' is also available, and it allows the AI to control an allied side.
