Sigonyth: Desert Eternity was a sci-fi MMORPG in development by New Desert. Set on a red hot, desert planet Sigonyth where the descendants of colonists and current inhabitants of a colonization ship that set out 200 years before have settled. The game takes place fifty years later. Changed over time, the residents are a mix of Humans, Mutants, and Cyborgs, which are the game's three playable races. Each race will be different in terms of skill opportunities, as well as advantages and disadvantages over such things as item cost or race-based perks.

Arguments over government and fighting over resources has led to several factions springing up and sides to take. Advancement is skill-based, dependent upon practice of certain skills to grow them, instead of rigid classes or levels. The game did not have a main storyline, but instead side quests away from the main action for experience, as well as hunting. Developers New Planet also sought to implement player-controlled politics, housing, and much freedom around shaping characters and their existence within the world.

The development came to a halt in 2006 when the team ran out of money to finish the project.
