Balazar is a 3D adventure and roleplaying game which is the sequel to Arkanae. In the game's story, although the three Gods that created the world have been safely imprisoned in the magical crystal of Arkanae, new scepters have been reforged, giving birth to new Gods. The player must find the scepters and imprison the Gods in the Arkanae or free them forever by dropping the scepters in the Abyss. You'll have to find your way through the 7 worlds: the Echassian village, the Pompon forest, the great cathedral, the ice desert, the Arkanae citadel, the Abyss swamp and finally the Elven Forge.
Deliantra is an advancement of the crossfire multi-user RPG game. Unlike the original project, it focuses mainly on stability and playability, but also adds modern technology such as map scripting, Perl server extensions, asynchronous I/O, higher resolution graphics, and better client support.
Sauerbraten (a.k.a. Cube 2) is a free multiplayer/single player first person shooter, built as a major redesign of the Cube FPS. Much like the original Cube, the aim of this game is not necessarily to produce the most features and eye candy possible, but rather to allow map/geometry editing to be done dynamically in-game, to create fun gameplay and an elegant engine.
