Space Sagas

Space Sagas is an idea for a large multiplayer mobile game where users can collaborate together to expand the intergalactical human empire. This game is set in the future when humanity has left Earth and is colonizing other planets, systems and galaxies.

Note that this game idea is far too ambitious for the first OGE game, requiring a large player base. Maybe some time in the future.

Every player plays as a singular character in the empire, starting as a humble troop and trying to progress to better ranks, including, commander, general and eventually admiral. The entire universe is multiplayer, so there are no NPCs or bots pretending to be players. The player 'wins' a game when they reach admiral rank or complete another objective, and loses if their character dies. Character 'lives' last a short time: at most an hour or two of play time. After every life played, the player unlocks new roles that the character couldn't become before (e.g. a double agent), and also knowledge and items that can be used for a boost in a life.

Admirals are in charge of fleets, and can set missions for their generals. Generals are in charge of completing missions, taking commanders and troops with them. Missions include: gathering resources, fighting enemies, making planets habitable and colonizing territory. Missions, like all the game, are multiplayer: all the troops, commanders and the general are real people, not bots. Missions last several days.

Alternatives
Lives could be longer or even one life could fill the whole game.
