Infinity Kingdom is a cartoon-style MMO strategy game where you play a resourceful lord rebuilding a city in the land of Norheim, fending off the invading gnomes and rival players. It blends classic 4X kingdom-building and alliance warfare with a hero-collection twist: you summon 50+ historical "Immortals" (Cleopatra, Julius Caesar, Merlin, Genghis Khan and more) and hatch seven elemental dragons, then assemble element-based armies for real-time tactical battles. Progression runs through castle upgrades, troop training, KVK cross-server wars, and a deep gear/energy-core system that has expanded over the years into the Level 60 "Legendary Season."
Our take
Infinity Kingdom is a slicker, more colorful take on the Rise of Kingdoms / Evony template, and its Immortal-plus-dragon collection layer gives team-building real personality that most gray-brown strategy MMOs lack. But it is a hardcore, PvP-driven live-service game built around KVK wars, timers, and a monetization curve that rewards spending heavily, which is exactly why its Steam reviews sit at "Mixed" with a Very Negative recent trend as veteran players react to power creep and the grind of the Legendary Season. If you enjoy alliance politics and don't mind a whale-heavy economy, there's a genuinely fun strategy game here; if you want a relaxed builder or a fair free-to-play climb, look elsewhere.
