City States: Medieval Launches on Steam Early Access — Trade, Sieges & Grand Strategy (April 20, 2026)

City States: Medieval Is Live On Steam Early Access Reverie World Studios and publisher indie.io officially launched City States: Medieval into Steam Early Access on April 20, 2026 at 11:00 UTC . The hybrid strategy game throws you into the cutthroat trade, diplomacy, and warfare of the 12th century , where you lead a single city state trying to survive between the giant kingdoms of Europe, North Africa, and the Middle East. It's a bold pitch: combine grand strategy, real time tactical combat, and tower defense siege mechanics into one game. Reverie World Studios, based in Toronto and founded in 2007, is the team behind the long running Kingdom Wars series . City States: Medieval is their most ambitious project yet — and it's part of the indie.io Franchise Sale at launch, which means there's a meaningful discount waiting for early adopters.

What Makes City States: Medieval Different Most medieval strategy games put you in command of an entire kingdom. City States flips the script — you lead a single city state trying to survive between the empires . That framing changes everything about how the game plays. You're not conquering Europe. You're navigating it, playing the trade routes, religious strife, and shifting alliances of the 12th century to carve out a mercantile empire. Power comes from commerce first, then diplomacy, then war — and only when those first two fail. Core Systems At Launch City building — grow through economy, military, faith, and trade building chains. Mercantile empire — build trade networks across Europe, North Africa, and the Middle East. Hybrid siege system — real time tactical combat fused with tower defense mechanics. Hero system — a single ruler leads your state with dual presence/absence mechanics. Dynamic 12th century — religious strife, rival kingdoms, Middle Eastern trade cities. The Hero System — The Mechanic That Sets City States Apart The Hero mechanic is City States: Medieval's headline feature, and it forces a strategic rethink on every turn. Your hero is a historical leader who anchors your city state — but they can't be everywhere at once. When your hero is present: you have full control over the city, territory, and armies, plus powerful bonuses. When your hero is away: you have limited command capacity, and the city state runs on a maintenance government with reduced efficiency. That means every expansion, every diplomatic mission, every trade negotiation is a high risk, high reward gamble . Send your hero to secure a trade agreement abroad and you open your city to opportunistic sieges. Keep them at home and you stagnate. It's the kind of asymmetric pressure that gives grand strategy its replay value. Hybrid Siege Combat — RTS Meets Tower Defense Reverie's Kingdom Wars pedigree shows up in the siege system . When your city state gets attacked — and it will, because wealth attracts predators — you drop into a real time tactical battle that layers tower defense mechanics on top of classic RTS combat . Fortifications, wall placement, and garrison management matter as much as unit micro. It's a genuine hybrid rather than a gimmick, and it's the kind of system that could make City States a sleeper hit with Stronghold and Total War fans looking for something mechanically fresh. Is City States: Medieval Worth Buying On Day One? Yes — if you're a grand strategy fan who enjoys Early Access development arcs. The launch build is Reverie's most mechanically ambitious project, the team has a demonstrated track record with Kingdom Wars, and the indie.io Franchise Sale discount makes the entry price easier to justify. Keep in mind this is Early Access , which means: Expect systems to evolve over the coming months. Balance passes will keep shifting the meta. New content (scenarios, heroes, regions) will roll in over time. Your feedback genuinely influences development — this is prime time to shape the game. If you prefer to wait for 1.0 stability, the game will only get better from here. If you like being early on a promising strategy sleeper, today's the day. Best Medieval City States To Lead In Early Access Historical flavor matters a lot in this genre, and the 12th century roster includes some of history's most compelling mercantile powers: Venice — the archetypal trade republic, perfect for naval commerce builds. Genoa — rival of Venice, strong in Mediterranean trade. Novgorod — eastern trade gateway with unique geography. Damascus — Middle Eastern cultural and trade hub. Lübeck — Hanseatic League entry point.
