$9.99 ~115.2 hr median no co-op complexity: heavy 91.2% of 26k
The Squirrel's verdictWorkers & Resources: Soviet Republic centers on the same overhead colony-management and production-chain puzzle as InfraSpace, but the Cold War-era setting means importing resources, managing finances, and building supply routes are active challenges rather than background systems. It is substantially deeper and harder, with a median playtime around 115 hours and a Very Positive rating at 91.2%.
Not for you if you want streamlined systems rather than hundreds of hours of trial-and-error managing imports, transport routes, and finances.

City BuilderColony SimAutomation
$24.99 ~34.3 hr median co-op complexity: moderate 85.6% of 1k
The Squirrel's verdictThe Colonists is a Settlers-style colony builder where robot colonists haul resources along roads through tiered tech progression — no combat, no crisis events, just transport-and-production optimization. It shares InfraSpace's overhead perspective and resource-chain focus but wraps them in a narrower, cozier structure. Steam rating is Very Positive at 85.6%, with reviews arriving as recently as 24 days before this writing.
Not for you if you need combat or crisis events to stay engaged, or inefficient AI hauler routing will frustrate you.

Closest Match Closest MatchThe most similar game to the anchor, by what players say.
Base-BuildingAutomationMinimalist
$12.99 ~8.3 hr median no co-op complexity: moderate 81.1% of 721
The Squirrel's verdictMini Settlers narrows InfraSpace's factory-routing puzzle down to fixed campaign maps with road-based hauling and tiered production chains — no city management, no survival layer. Each map starts fresh with no carryover from previous levels. Median playtime is around 8 hours, and reviews note that roads carry only one resource type, which creates bottlenecks in later stages.
Not for you if you want open-ended colony building or progression that carries between levels, since every map resets completely.
4
TransportationEconomyCapitalism
$19.99 ~20.6 hr median co-op complexity: moderate 79.3% of 545
The Squirrel's verdictWorldwide Rush centers on transport-route planning — assigning vehicles, setting lines, and balancing passenger demand across a growing network — with no factory or production chains involved. It shares the logistics-optimization appeal of InfraSpace but applies it to a transport-tycoon structure. Reviews consistently flag passenger routing logic that becomes unreliable in longer sessions.
Not for you if you need reliable passenger-routing feedback, or demand logic that stops making sense mid-session will end your run.
5
City BuilderColony SimImmersive Sim
$29.99 ~22.1 hr median no co-op complexity: moderate 77.5% of 1k
The Squirrel's verdictBoth games layer production-chain logistics under a city-builder skin, forcing supply-and-demand math instead of pure zoning. Highrise City frames this as a vertical city with resident satisfaction tied to goods flow, closer to Anno than to Cities Skylines. It suits players who want InfraSpace's logistics puzzle wrapped in denser urban management.
Not for you if frequent crashes and performance drops during long sessions will break your patience with a logistics-heavy city builder.
6
City BuilderTransportationTrains
$19.99 ~31.4 hr median no co-op complexity: moderate 77.4% of 1k
The Squirrel's verdictTransit logistics rather than factory automation defines Cities in Motion: you design bus, tram, and metro routes to move passengers through a growing city, not production chains through a colony. The core challenge is matching supply to demand across an expanding network. Reviews flag a persistent late-game metro bug where trains stop loading properly, which can make major stations unworkable.
Not for you if you want factory or colony management mechanics, or late-game pathing bugs will end your session.
7
TransportationEconomyResource Management
$11.99 ~9.6 hr median no co-op complexity: light 69.8% of 1k
The Squirrel's verdictInfraSpace is factory logistics with production chains and infinite resource patches to optimize. Transport INC drops that for transport-network logistics: setting bus/plane/cargo routes between cities, pricing tickets, and managing a growing vehicle fleet. Same appetite for building and tuning a system, no base-building or manufacturing chains, and demand between cities is randomly assigned rather than chosen.
Not for you if you want manufacturing and production chains rather than routing vehicles between fixed cities, or you plan to scale past thirty vehicles.

TransportationCity BuilderEconomy
$19.99 ~12.5 hr median co-op complexity: moderate 58% of 3k
The Squirrel's verdictInfraSpace fans came for logistics-optimization layered under a city builder; Cities in Motion 2 strips that down to pure transport-network puzzle-solving, no factory chains or colony survival attached. You design routes, timetables, and vehicle mixes across buses, trams, and metro to move citizens efficiently. It's slower-paced and narrower in scope, built for people who want the logistics puzzle without the base-building.
Not for you if you came to InfraSpace for production-chain and colony management rather than transport-route optimization, or you need fast pacing over hours of triple-speed grinding.
