Summary

OGame is a browser-based, money-management and space-war themed massively multiplayer online browser game with over two million accounts. OGame was created in 2002 and is produced and maintained by Gameforge. Players can have multiple planets a fleet and attack each other to steal resources. Different kind of playing styles are possible, for example someone could adopt a peaceful playing focusing on mines development and exchange of resources, while other could engage in a more aggressive style developing massive fleets to crash some others and steal their resources.

Ogame Cairo will be an incomplete information 100% on chain, planets are NFTs and resources ERC20 tokens. ERC1155 will be implemented to represent fleets of different kinds of ships. This will massively improve the UX and will provide ownership of the assets that a player will spend time developing and or money to buy it from others.

The original version of the game is still live, but in the recent years pay to progress options have been introduced, it goes without saying that this ruined the gameplay.

Game Play

Planets

Each planet will be an unique NFT with different levels of rarity that will effect the game play, eg. size of the planet, surface temperature. More specific details are still to be worked out, but the design space is pretty much infinite here. Ehach player will have to receive a planet from the manager smart contract prior start playing, this functionality is already implemented in the current version of the game.

Resources

There are 3 type of resources:

• Metal: Metal is the primary resource used in the foundation of your Empire. At greater depths, the mines can produce more output of viable metal for use in the construction of buildings, ships, defense systems, and research. As the mines drill deeper, more energy is required for maximum production. As metal is the most abundant of all resources available, its value is considered to be the lowest of all resources for trading.
• Crystal: Crystal mines supply the main resource used to produce electronic circuits and from certain alloy compounds. Mining crystal consumes some one and half times more energy than a mining metal, making crystal more valuable. Almost all ships and all buildings require crystal. Most crystals required to build spaceships, however, are very rare, and like metal can only be found at a certain depth. Therefore, building mines in deeper strata will increase the amount of crystal produced.
• Deuterium: Deuterium is also called heavy hydrogen. It is a stable isotope of hydrogen with a natural abundance in the oceans of colonies of approximately one atom in 6500 of hydrogen (~154 PPM). Deuterium thus accounts for approximately 0.015% (on a weight basis, 0.030%) of all. Deuterium is processed by special synthesizers which can separate the water from the Deuterium using specially designed centrifuges. The upgrade of the synthesizer allows for increasing the amount of Deuterium deposits processed. Deuterium is used when carrying out sensor phalanx scans, viewing galaxies, as fuel for ships, and performing specialized research upgrades.

Each one of the resources is produced by its specific mine, each mine can be developed separately, each mine level has an increasing cost and an increase in production. The resources production is defined by a formula, eg. ((6 * mine_level) * (11mine_level)) / 104 is the formula for the metal production. Metal is produced faster than crystal and deuterium hence considered the cheapest. There’s no limit to the level a mine can be developed but the cost of advancing a mine does not scale linearly with the production amount so that over a certain level is not economically viable to increase the mines levels and other means to gain resources must be found.

Example of metal mine cost and production progression.

Production and Profit vs Cost

If you build a level 13 metal mine it will take around 5 hours to get back the metal used to build that level.

Facilities

There are four main facilities:

• Robotics Factory: The Robotics Factory primary goal is the production of State of the Art construction robots. Each upgrade to the robotics factory results in the production of faster robots, which is used to reduce the time needed to construct buildings.
