Squirrel's Pick Squirrel's PickThe best game on this page. If you only try one, try this.
AutomationSpaceBase-Building
$19.99 ~142.3 hr median no co-op complexity: heavy 97.5% of 91k
The Squirrel's verdictDyson Sphere Program scales factory automation from a single planet's ore belts up through interplanetary logistics to a star-consuming Dyson sphere — a scope Foundry doesn't attempt. Building and belt placement are more refined, and the single-player campaign runs around 142 median hours. The mid-game transition gets awkward before it smooths out, and content updates have been sparse since the main release.
Not for you if you want multiplayer, or combat and exploration woven into the factory loop.

AutomationFuturisticPuzzle
$29.99 ~41.7 hr median no co-op complexity: moderate 97.2% of 15k
The Squirrel's verdictBoth are belt-and-machine factory builders about scaling production, but shapez 2 strips out foundation-clearing, exploration, and combat entirely: you build on an open grid with abstract shapes as the only resource. Controls and blueprint tools are more refined than Foundry's, at the cost of any survival or base-defense layer.
Not for you if you want the physical world-building, resource scavenging, or survival threats that shapez 2 deliberately leaves out.

Hidden Gem Hidden GemLoved by the players who found it, but still under the radar. Budget Pick Budget PickThe best game here for the least money.
AutomationMedievalCrafting
$17.99 ~70.2 hr median co-op complexity: moderate 89.9% of 2k
The Squirrel's verdictRunning a shopkeeper operation sits at the center of Alchemy Factory: store reputation rises and falls based on whether shelves match customer demand, and that demand shapes what your factory must produce. Compact voxel-scale optimization and conveyor logistics are still present, blueprints make refactoring manageable, and co-op is supported. Median playtime is around 70 hours, though mid-game profitability draws complaints.
Not for you if you want pure factory optimization without a reputation-decay shop system controlling your production targets.

Closest Match Closest MatchThe most similar game to the anchor, by what players say.
AutomationBase-BuildingSpace
$18.99 ~40.1 hr median co-op complexity: moderate 85.1% of 808
The Squirrel's verdictOutworld Station shares Foundry's factory-building core: production chains, logistics, base expansion. Unlike Foundry's open sandbox with no combat, it adds enemies whose power level rises over time and structures progress as a mission-by-mission campaign across small, fixed-resource maps rather than open-ended world building. Co-op is supported.
Not for you if you prefer open-ended sandbox building over a mission-by-mission campaign with small, fixed-resource maps and no blueprint tool.
5
Base-BuildingAutomationResource Management
$19.99 ~40.6 hr median co-op complexity: moderate 80.9% of 3k
The Squirrel's verdictAstro Colony shares Foundry's calm automation loop: no combat, no exploration pressure, just building and connecting production chains. It adds co-op and a space-asteroid setting instead of voxel terrain, but carries similar wiring friction (L-shaped runs need two separate segments) and an unevenly paced tech tree. Median playtime sits at 40.6 hours, shorter than a deep factory sink.
Not for you if you want blueprints and streamlined wiring instead of manual segment-by-segment cable placement, or a long factory-game runtime.
6
CraftingAdventureBase-Building
$14.99 ~59.7 hr median no co-op 83.4% of 391
The Squirrel's verdictEvospace shares Foundry's voxel factory-building in a procedurally generated world you dig through and automate, with the same no-combat, exploration-over-fighting pace. Machines, conveyors, and logistics chains work similarly. The difference: resource gathering stays manual longer here, and it's a solo developer's project rather than a larger studio effort. No co-op.
Not for you if you want blueprints, streamlined building placement, or multiplayer, since Evospace still leans on manual resource gathering and solo-dev pacing.

AutomationBase-BuildingResource Management
Strong Mods Strong ModsA deep, active modding scene extends it past its base content.
$18.99 ~16.4 hr median no co-op 79% of 305
The Squirrel's verdictPlayers who want automation's research-and-logistics structure without voxel terraforming or land-clearing will find Final Factory's space setting fits: you pilot mobile bases to resources rather than expanding outward from a fixed plot. Item routing works differently from standard conveyor norms, and reviews flag the transport system as restrictive and the mechanics as poorly documented. Median playtime runs around 16 hours.
Not for you if you want flexible logistics, clear in-game documentation, or more than 20 hours of content before the systems frustrate rather than engage.

AutomationSpaceBase-Building
$19.99 ~34.6 hr median no co-op complexity: heavy 76.9% of 458
The Squirrel's verdictFinal Upgrade is a logistics puzzle with defined goals rather than Foundry's open-ended sprawl: you expand toward specific objectives instead of clearing land and repeating layouts indefinitely. Reviewers note a confusing tutorial and cluttered UI on first contact. Median playtime sits around 34.6 hours, shorter than the anchor's endless-expansion loop.
Not for you if you want Foundry's open-ended factory scale rather than a bounded, objective-driven logistics puzzle with a rough onboarding.
