The game has been officially decomissioned and the code has been open sourced for those who are curious.

Imperial Kingdoms was a clone of Xenocide3001, a futuristic space-combat game of research, building, diplomacy, and conquest. Play happened in real-time but at a pace that allowed players to only have to check in a few times a day usually. The goal of the game was to research new technologies, build your planet infrastructure, and produce armies and space fleets to conquer other worlds and players.
