Aleryos and OGame are two free space strategy games played in a browser. In both, you develop planets, produce resources, research technologies, build fleets, and join alliances in a shared universe.
I develop Aleryos, so this comparison is not neutral. It describes the features presented by official sources consulted on October 24, 2026, without ranking either game, promising balance, or concluding that a feature missing from a presentation page is missing from the game.

Where the two games are alike
In both games, you develop planets, research technologies, build fleets, and play with or against other players in shared universes. Alliances add a collective dimension to individual progress.
Both games are free to play in the browser and offer a mobile app. Access alone does not summarize the experience, however: the role of ships, collective systems, and available activities lead to different decisions.
What Aleryos highlights
Aleryos combines five human factions, skills acquired with Echoes, pacts between alliances, and technologies funded through member donations. The Federation Market and pact-based exchanges also give player trade a place.
Pillars project ground forces from one planet to another for attacks, exploration, espionage, piracy, and colonization. This ground front has its own units and rules, separate from space combat.
Before producing a ship, you design its model: a chassis receives hulls, reactors, weapons, and shields. The volume devoted to components reduces available cargo, then direct construction or assembly turns this plan into ships.
What OGame highlights
OGame has been playable in a browser since 2002. Gameforge presents progression based on resources, technologies, colonization, alliances, and space battles in shared universes.
Choosing a class guides the empire’s specialization. Official pages about ships describe several combat and civilian ships, their uses, prerequisites, and rapid-fire interactions.
That longevity and continuity of service matter to players looking for an established browser-based space strategy game.
How purchases work
Aleryos is free to play. Its store offers consumables, packs, premium packs, and cosmetics. Astrium purchases show their cost and effect; they do not rely on a random draw. A shared monthly cap applies to some direct consumable purchases, while premium packs are excluded. The Smuggler is a system separate from the store.
OGame is also free to play. Gameforge presents an optional Dark Matter shop for convenience features and describes officers among the uses of that currency.
Which should you choose?
Choose OGame if you are looking for a space strategy game active since 2002, centered on planetary economy, research, fleets, and alliances, with iOS and Android apps.
Choose Aleryos if you want to design your ship models, choose a faction, fund alliance technologies, and add ground operations to space missions, in the browser and on Android with the same account.
These pointers describe gameplay priorities. They are neither an overall ranking nor a guarantee about the balance, pace, or convenience of each universe.
Frequently asked questions
Is Aleryos like OGame?
Yes, in its foundation: planets, resources, research, fleets, and alliances in a shared universe, free to play in a browser. Aleryos also develops factions, alliance technologies, player-designed ship models, and a ground front.
What is the difference between OGame and Aleryos?
Aleryos brings together factions, pacts, alliance technologies, ship design, and operations through Pillars. OGame highlights its history since 2002, its classes, lifeforms, ship catalog, and space battles.
Is Aleryos free like OGame?
Yes, both games are available for free. Aleryos offers optional Astrium purchases: consumables, packs, premium packs, and cosmetics. Some direct consumable purchases share a monthly cap, from which premium packs are excluded.
How do the two games present combat?
Aleryos separates space combat from ground operations carried out through Pillars. The OGame official sources consulted present fleets, defenses, and space battles; this comparison does not infer that a feature is absent merely because it is not documented on those pages.
Can you create your own ships?
In Aleryos, the player composes a model from a chassis and components. OGame’s official pages instead present a catalog of civilian and military ships with their roles, prerequisites, and uses.
Can you play Aleryos and OGame on mobile?
Yes. Aleryos offers an Android app with the same account as in the browser. OGame offers an official app on iOS and Android.
