AutomationSpaceBase-Building
$19.99 ~142.3 hr median no co-op complexity: heavy 97.5% of 91k
The Squirrel's verdictDyson Sphere Program is the genre Star Birds drew from, without the build-slot caps or crossing restrictions: belts tangle into spaghetti at scale, production chains span multiple planets, and the goal stretches to building an actual Dyson sphere around a star. The 97.5% positive Steam rating and 142-hour median playtime reflect how far the scope extends. No co-op is available.
Not for you if you want co-op, short structured missions, or a game you can finish in an evening rather than a hundred-plus hours.

Prospector: The First Contract
PC
Open World Survival CraftSurvivalAutomation
~3.9 hr median no co-op 91.8% of 503
The Squirrel's verdictProspector: The First Contract is an open survival sandbox where crafting chains gate progress through tethered asteroid terrain, solar storms, and hostile enemies — friction Star Birds never introduces. Some automation is present but partial; reviewers note the game actively resists full automation in places. Steam rating is Very Positive at 91.8%, though median playtime sits under 4 hours and no co-op is available.
Not for you if you wanted structured mission objectives rather than open survival, or dislike combat and environmental hazards mixed into resource logistics.

AutomationBase-BuildingSpace
$18.99 ~40.1 hr median co-op complexity: moderate 85.1% of 808
The Squirrel's verdictOutworld Station pairs level-by-level factory objectives with ship-building and RTS-style enemy pressure, plus co-op. It reached v1.0 with a median playtime near 40 hours and an 85.1% positive rating. Reviewers describe fixed maps, limited resource-point placement, and objectives that amount to waiting out production queues rather than redesigning systems.
Not for you if you want genuine automation complexity and scaling rather than fixed maps with predetermined resource points and incremental enemy pressure.

Closest Match Closest MatchThe most similar game to the anchor, by what players say.
CollectathonExplorationRogue-lite
$12.99 ~27.2 hr median no co-op complexity: light 84.4% of 936
The Squirrel's verdictBoth put you mining and upgrading across alien terrain, but Star Birds forces spatial puzzle-solving around pipe layouts while Galactic Mining Corp strips that out for mouse-only clicking and stacked upgrades. Median playtime runs 27.2 hours. This suits players who want the resource-collection loop without the asteroid-space constraints, not the automation puzzle itself.
Not for you if you wanted the layout puzzle and spatial constraints of automation games rather than a click-and-upgrade progression loop.
5
Base-BuildingAutomationResource Management
$19.99 ~40.6 hr median co-op complexity: moderate 80.9% of 3k
The Squirrel's verdictAstro Colony extends the asteroid-automation premise into a continuous open base that persists and grows across a full tech tree, with co-op supported. Pipe and belt networks still feed factories, but there's no mission boundary forcing you to start over — just a sprawling build that reviewers log around 40.6 hours completing. Wiring is clunky and tech pacing is uneven throughout.
Not for you if you prefer bounded puzzle levels over open-ended base expansion, or expect polished wiring tools and consistent progression pacing.

Colony SimResource ManagementCity Builder
$2.99 ~6.8 hr median no co-op complexity: moderate 81.8% of 1k
The Squirrel's verdictBoth build production chains across constrained layouts where every connection point is scarce. Blueprint Tycoon adds SpaceChem-style instruction puzzles inside each building alongside placement and ratio management, and drops the story/tycoon/puzzle identity crisis for a single focused automation loop across discrete scenarios rather than an open space setting.
Not for you if you want an evolving open map instead of bounded scenario levels, or expect blueprint optimization to meaningfully change output beyond the default setup.

$19.99 ~29.7 hr median no co-op complexity: moderate 80.5% of 796
The Squirrel's verdictKubifaktorium's defining layer is colonist management: workers must be assigned to task categories, routed between stockpiles, and kept from wasting movement across the map — logistics that sits on top of, rather than inside, the automation puzzle. It's a full 2021 release at $19.99 with a Very Positive rating and 29.7 median hours logged, though reviewers note the island structure repeats objectives without meaningful progression between areas.
Not for you if you want deep automation scaling, or find manual stockpile-and-transport micromanagement tedious rather than engaging.
