ESDAO is a massively multi-player wargame
Games typically involve 8-12 players and last about 40 turns. You have 24 hours to do each turn, meaning games are played out over weeks and months rather than hours.
You begin in a single hex and use your initial resources to take over neighboring hexes and develop their production. This repeats for a few turns until you encounter other players.
ESDAO isn’t a game where you can just attack everyone and expect to survive, you must negotiate with some to become allies allowing you to concentrate your forces when attacking others.
