$8.99 ~65.9 hr median no co-op complexity: moderate 94.6% of 37k
The Squirrel's verdictAgainst the Storm rebuilds from scratch each run, asking players to choose what to produce based on available orders, resource pools, and population types rather than developing everything. Production chains are harder to manage, and runs can fail. Median playtime reaches around 66 hours across many short sessions. Players who want repeatable variety and escalating difficulty in a city-builder format will find it here.
Not for you if you want a single continuous build rather than repeated runs with harder resource decisions and real failure conditions.

$19.99 ~37.2 hr median no co-op complexity: light 93.5% of 31k
The Squirrel's verdictBuilding castle walls, towers, and defensive structures against raider attacks defines Kingdoms and Castles. Raiders will assault unless you toggle chill mode to disable combat entirely, replacing SteamWorld Build's underground exploration with siege defense on a continuous overland map. No co-op. Reviewers note the loop can feel exhausted well before median playtime, which sits around 37 hours.
Not for you if you want underground mine exploration rather than castle construction and surface-level raid defense.

City BuilderFuturisticSci-fi
$17.99 ~51.1 hr median no co-op complexity: moderate 87.3% of 4k
The Squirrel's verdictCliff Empire places isolated cliff cities on separate budgets, forcing them to trade with each other through a market economy. Reviews flag that economy as confusing: resource categories are unclear, and some items the game classifies as non-food (fruits, fish, greens) do not count toward food goals. Players who want opacity and a steeper resource challenge over SteamWorld Build's guided systems will find more friction here.
Not for you if you want clear resource classification and guided mechanics rather than an economy where key rules go unexplained.

City BuilderBase-BuildingExploration
$24.99 ~10.9 hr median no co-op complexity: light 86.7% of 2k
The Squirrel's verdictA flying city that must stay airborne — balancing lift against weight while gathering resources and keeping citizens content — is the entire structure of Airborne Kingdom. There is no mine-exploration half and no worker-priority system; workers cannot be unassigned from buildings without demolishing them. Reviewers describe late-game as repetitive and low-challenge. Playtime averages around 11 hours.
Not for you if you want worker management tools, a two-mode structure, or a genuine late-game difficulty ramp.

$13.79 ~15.9 hr median no co-op complexity: light 89.5% of 590
The Squirrel's verdictBoth are low-stress city builders where district placement and production chains matter more than crisis management. City Tales drops the mine-exploration loop and any survival pressure entirely: no food consumption, no needs tracking, districts auto-fill with housing. If SteamWorld Build's ease was the appeal rather than the complaint, this goes further in that direction.
Not for you if you wanted SteamWorld Build's mining layer or any population needs and resource strain to manage.

$24.99 ~15.6 hr median no co-op complexity: moderate 81.9% of 1k
The Squirrel's verdictLaysara's fixed mountain terrain turns city layout into an optimization puzzle: resources must feed upward through vertical tiers, and early placement choices carry lasting consequences. Reviews describe it as closer to a puzzle game than a traditional city builder, with tight resource math replacing open-ended expansion. There is no mine-exploration mode. Players who want dense logistics and layout challenges will find more constraint here than in SteamWorld Build.
Not for you if you want open-ended city growth and low-stakes pacing rather than fixed terrain that punishes suboptimal layouts.

City BuilderColony Sim
$15.99 ~19.2 hr median no co-op complexity: moderate 82.6% of 413
The Squirrel's verdictFour playable cultures, invading neighbors, and military conflict built into the construction loop are what distinguish Hearthlands from SteamWorld Build's cave-and-surface format. Supply chains are less transparent and neighbors will invade, requiring military builds alongside economic ones. The campaign introduces mechanics steadily, and a sandbox mode is available. Suited to players who want system depth and pre-built conflict without co-op.
Not for you if you prefer clear tutorialization and no real invasion threat over an unforgiving supply chain and military pressure.

Dream Engines: Nomad Cities
PC
City BuilderSurvivalAutomation
$11.99 ~20.4 hr median no co-op complexity: moderate 73% of 622
The Squirrel's verdictDream Engines pairs city management with resource-gathering exploration, the same two-mode structure as SteamWorld Build, but wraps it in escalating difficulty: fuel demands force expansion, threat levels rise over time, and city layouts often need rebuilding between maps. Reviews flag combat as bare-bones and core mechanics as underexplained. Players who want stakes attached to the city-builder loop will find more pressure here.
Not for you if you want SteamWorld Build's low-pressure pacing — reviews describe mandatory city rebuilds, lackluster combat, and poorly explained mechanics.
