Since the duration of the game is limited, but the number of planets is effectively unlimited, players are encouraged to be highly aggressive at all times.
Players log in and make their moves and purchases, then the moves, battles and economic changes are calculated by the server (the "Acutron") at a set time during the day (or, for player-owned PUB games, whenever they choose), at which point a new turn starts.
Technology takes the form of unit "licenses" purchased on a planet, representing production and training facilities.
Other than graphics, the only differences between the races are their starting homeworld, unit types and licences owned.
Early game, each race has a distinctive strategy dictated by what technology is available.
