AutomationPhysicsMining
$14.99 ~23.6 hr median no co-op complexity: moderate 96.3% of 4k
The Squirrel's verdictMineMogul is a compact automation builder where resources are physical objects with actual collision rather than abstracted numbers moving through a system. Conveyors can jam; cross-contamination produces scrap. Reviews consistently praise the physics-driven feel but note limited overall content scope, with median player hours around 23.6 according to platform data.
Not for you if you want deep economic systems or long-term progression — reviews describe it as tightly scoped and short-lived.

Strong Mods Strong ModsA deep, active modding scene extends it past its base content.
$19.99 ~53.3 hr median no co-op complexity: moderate 90.7% of 4k
The Squirrel's verdictFactory Town shares Alchemy Factory's core loop of building automated production chains and optimizing layouts, but drops the shopkeeper and reputation-decay system entirely. Workers and vehicles move goods with no time pressure and no punishment for mistakes, making it suited to players who want factory logic without economic-management stress. Campaign levels repeat structure; sandbox mode is where the depth shows.
Not for you if you want the shopkeeping and reputation-decay pressure that defines Alchemy Factory's mid-game, since Factory Town removes deadlines and penalties entirely.

Hidden Gem Hidden GemLoved by the players who found it, but still under the radar.
AutomationBase-BuildingCrafting
$4.99 ~31 hr median no co-op complexity: moderate 90.4% of 250
The Squirrel's verdictBoth games hinge on tight-space optimization: compact grids, recursive machines that reuse and shrink production chains, and the pull to squeeze maximum output from minimal footprint. Assembly Planter drops the shopkeeping layer entirely, staying pure automation puzzle across 20 levels, but reviews consistently flag an unfriendly, anti-QoL interface as the price of entry.
Not for you if you need the shop/customer-reputation layer Alchemy Factory has, or you can't tolerate a UI reviewers call actively hostile to learn.

Resource ManagementEconomyAutomation
$19.99 ~30.1 hr median no co-op complexity: moderate 83.6% of 3k
The Squirrel's verdictWorker management and repair-order contracts define Little Big Workshop's economy rather than any shopkeeping or reputation loop. You assign staff to workstations, lay out zones during a planning phase, and fulfill production orders from clients. Reviewers praise the presentation but flag an unresolved no-profit bug and a lack of in-game guidance that frustrates experienced players trying to optimize.
Not for you if you need clear bug resolution and in-game optimization guidance — reviewers cite both as persistent gaps.

AutomationBase-BuildingResource Management
Strong Mods Strong ModsA deep, active modding scene extends it past its base content.
$29.99 ~52.2 hr median co-op 80.9% of 4k
The Squirrel's verdictFoundry is an open 3D voxel factory sim focused on routing materials through conveyors and pipes across excavated terrain, with no shopkeeper economy or store reputation to manage. Co-op is supported. Reviews note that placing conveyors, pipes, and wiring feels awkward and that the QoL falls short of more established factory games, making large rebuilds tedious.
Not for you if you came for tight grid optimization and a retail-economy layer — Foundry has neither, and reviewers flag its building tools as friction-heavy.

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 Alchemy Factory's core loop: build production chains, automate resource flow, unlock new machines as you scale. It drops the shopkeeper/reputation layer entirely and adds combat against AI opponents with rising power levels, plus co-op play. Progression is mission-gated and linear rather than an open sandbox for recursive optimization puzzles.
Not for you if you came for open-ended layout optimization rather than fixed-level missions, and want a blueprint tool for repetitive building.

AutomationResource ManagementBase-Building
$19.99 ~34.5 hr median no co-op complexity: heavy 78% of 150
The Squirrel's verdictBoth pair factory optimization with running a profitable business rather than pure production. Titan drops the physical avatar entirely, making you an omnipresent faction CEO managing debt and monetary priorities from the start, with maglev-based logistics replacing conveyor layouts. Suits players who liked Alchemy Factory's shopkeeper-sim half more than its factory half.
Not for you if you want to walk around your factory as a character, or you're tired of manually managing constant financial pressure instead of automating it away.

EconomyResource ManagementAutomation
$24.99 ~24.6 hr median co-op complexity: moderate 73.5% of 2k
The Squirrel's verdictGood Company pairs factory layout with hiring staff, conducting R&D, and hitting campaign milestones — closer to a full business simulation than a pure production puzzle. Co-op is supported. Reviews flag error-prone retooling when upgrading product lines and a logistics system some find convoluted, alongside bugged milestone tracking in campaign levels.
Not for you if you want direct, readable control over goods routing or find milestone-gated campaign structures more frustrating than motivating.
