Ogame

OGame is a strategy game set in space, with thousands of players from across the world competing at the same time.
All OGame universes consist of three classifications: galaxies, systems, and planet slots (which break down to planets, moons, and debris fields). All universes have up to 9 galaxies, each with 499 (1-499) systems, which have 15 planet slots.
Each player starts with one planet at randomly assigned coordinates in slots 4,6,8,10,12, in a random system and galaxy. The first planet always consists of 163 fields, which determine how many building upgrades can be built on the planet, regardless of the slot in the player's system. Originally, the player's empire could consist of up to 9 planets in any unoccupied planet slot. However, with the redesign, that cap was lifted, albeit with the requirement that each planet required two additional levels of research, with a progressive cost. All construction, research, and missions are performed and launched from a planet or moon. Development is done through using five resources: metal, crystal, deuterium, energy, and dark matter. There are different ways to obtain these resources, including mining, trading, and raiding (see Combat below). Players are ranked according to their points, with one point awarded for every thousand resource units invested in construction, research, ships, or defense. No points are given for unspent resources.
