Quick answer
OGame is the classic 4X space strategy standard since 2002 with massive legacy and stable balance. Xterium is the modern successor focused on alliance wars as the core mechanic, full-featured native mobile apps and three universes with different pacing. If you value stability and a legend — go OGame. If you want modern pacing, mobile play and active alliance dynamics — go Xterium.

Where OGame
Honestly: OGame does several things better than us. We acknowledge it explicitly.
Most-known game in the genre with 20+ years of legacy and literature
Huge community with regional servers worldwide
Mature balance — exploits long-since closed, meta well-understood
Wikipedia entry, academic case studies — undeniable authority
Where Xterium is stronger
What we do better — not marketing rhetoric, but verifiable differences.
Alliance wars — core mechanic, not an add-on
Native iOS + Android apps (OGame is browser-only on mobile)
Three universes on one account — different play styles without switching login
Open public knowledge base with formulas and stat-rich guides
Modern UI/UX — doesn't look like Web 2.0
Years of content: 19 tournament types on 6 parallel tracks, 363 missions, 68 contracts and 23 anomaly types
