OGame as Civilisation Experience

When thinking about civilisation building games, one thinks of technology trees, social development, economy and diplomacy. OGame offers all of this — in browser, without download, since 2002. The space strategy game is more than a shooting game: It's building a galactic civilisation from primitive single-planet economy to research-mighty multi-world society.

The Technology Tree: Civilisational Progress

Foundation Technologies

The first technology layer in OGame covers the basics: energy technology enables more efficient power plants, laser technology opens the way to defensive installations, computer technology increases the number of simultaneously controllable fleet commands. These technologies are relevant for every playstyle — nobody can do without them.

Propulsion Technologies: Civilisation Mobility

An advanced civilisation must be able to move. OGame represents this with three propulsion technologies:

Each propulsion research increases the speed of corresponding ships by 10% per level — a steady progress that accumulates over months.

Military Technologies: Civilisation Defence

Weapons technology, shielding technology and armour technology determine combat strength. These technologies are classic civilisation upgrades: Each level gives +10% to the corresponding value for all ships and defensive installations. Top players invest enormous resources in these technologies — at level 15–20 the costs become astronomical.

Scientific Peak: Graviton Research

Graviton research is the endgame of OGame technology development. It requires 300,000 energy units on a single planet — a challenge that only advanced civilisations can master. The reward: access to the Death Star, the most powerful ship in the game. Graviton research is proof of technological maturity.

Social Classes: Civilisation Specialisation

The class system represents social development in OGame. By choosing a class, the entire civilisation specialises:

Collector Civilisation

A society that places production over expansion. Resources flow in abundance, mines work at full capacity, crawlers boost production rates. A Collector civilisation is economically almost unbeatable — its strength is endurance and resource power.

General Civilisation

A society that relies on military superiority. Ships fly faster, fight stronger and clear debris fields more efficiently. A General civilisation is offensively oriented — it wins through direct confrontation and quick power projection.

Explorer Civilisation

A society that grows through expansion and discovery. More planets, further-reaching espionage capabilities and better expedition results make the Explorer civilisation the most flexible option. It gathers resources and ships from the unknown and controls more space than any other class.

Alliance Diplomacy: Politics of the Galaxy

OGame alliances function like city-states with their own foreign policy. NAPs (Non-Aggression Pacts) regulate peaceful coexistence, wars are conducted through coordination and ACS (Alliance Combat System). The Titan Clash events are galactic wars where alliances compete for overall victory.

This diplomatic level elevates OGame above pure economic or military games: Those who understand the galaxy politically and forge clever alliances win without owning the strongest Death Star.
