Short answer
Xcraft is a real-time browser RTS in the spirit of StarCraft, with three races and live micro. Xterium is a persistent space MMO strategy in the OGame tradition — economy, research, fleets and alliance wars that play out 24/7, across three universes on one account, with full native iOS and Android apps. If you love the space setting but want a persistent empire, an alliance meta and real mobile play instead of constant real-time control — Xterium fits.
Why Xcraft players try Xterium
Not better or worse — a different kind of space game. Here is what Xterium adds.
Persistent universe
Your empire keeps growing while you are away — no live match to babysit. Plan builds, research and fleet movements that resolve over hours.
Alliance wars as core
Dozens of players coordinate attacks, defense and diplomacy. Alliances are the central mechanic, not a side feature.
Full mobile apps
Native iOS and Android clients with push notifications and browser sync — manage the empire from your phone.
Three universes
War of Alliances, Classic, Reborn — different balance and tempo on one account. Pick the style that fits you.
Transparent economy
All combat, speed and cost formulas are open in the knowledge base — no hidden modifiers.
No pay-to-win
Premium is convenience, not power. Every strategy and victory is reachable for free.
