$23.99 ~71.4 hr median no co-op complexity: moderate 89.1% of 21k
The Squirrel's verdictGoing Medieval applies the pawn-management and verticality-based base defense familiar from colony sims to a medieval settler setting, with 3D construction and multiple building styles as its main creative draw. It holds a Very Positive rating at 89.1% and a median of 71.4 hours played. The developer team is described in reviews as actively listening to player feedback.
Not for you if you want a family or lineage system, or expect melee combat and pawn pathfinding to be more polished than a typical colony sim.

Base-BuildingSpaceColony Sim
$24.99 ~47.1 hr median no co-op complexity: moderate 85.8% of 11k
The Squirrel's verdictSpace Haven moves the colony-management loop onto spaceships: survivors need food, rest, and morale while players design, build, and defend a vessel in space rather than on a planet surface. Power routing, hull integrity, and ship layout replace terrain, biomes, and seasons as the primary environmental systems. It carries a Very Positive rating at 85.8% positive, with a median of 47.1 hours played.
Not for you if you want a smooth interface and gentle tutorial rather than a control scheme reviewers consistently describe as fighting you at every stage.

The Squirrel's verdictStardeus uses the same Rimworld-style loop of managing survivor needs, researching tech trees, and defending a base, but the setting is a damaged spaceship rather than a planet surface. Power routing, hull integrity, and ship layout replace terrain, biomes, and seasons as the main environmental systems. It carries a Very Positive rating at 87.0% positive, and players log a median of 53.8 hours. Reviews flag a research wall in the early game that gates basic survival needs including life support and sanitation.
Not for you if you want ground-level terrain and biomes rather than a ship interior, or dislike research walls gating basic survival needs in the early game.

$6.99 ~34.8 hr median no co-op complexity: moderate 80.7% of 2k
The Squirrel's verdictJudgment: Apocalypse Survival Simulation puts three survivors in a randomly generated world after a demon apocalypse, with base-building, crafting, scavenging expeditions, and research gates that require looting specific items to advance. Combat is central to every loop—reviews note the game is built around constant fighting and preparation for it. Priced at $6.99 with a median of 34.8 hours logged across players.
Not for you if you want combat to be optional rather than the constant grind the base-building loop is built around.

Sci-fiSurvivalColony Sim
$9.99 ~37.2 hr median no co-op complexity: moderate 78.5% of 316
The Squirrel's verdictMercury Fallen is a solo-developed colony sim where survivors wake underground on an alien planet and dig out their base while researching and managing pawns individually. The digging and underground construction are more central here than in most colony sims, and the scale stays small throughout. The last update was June 2024, after which the developer moved to a different project.
Not for you if you need late-game balance and ongoing content, since reviews describe stalled progression and no updates since mid-2024.

$14.99 ~30.9 hr median no co-op complexity: moderate 78.2% of 211
The Squirrel's verdictAfter the Collapse shares Z-level verticality with Stranded, letting terrain factor into defense without forcing killbox designs. The setting is post-nuclear rather than alien-planet, and the developer has maintained an active presence on forums and continued updating the game through its 1.0 release. Suits players who want a small-group base-building loop with expeditions and a colonial feel in an apocalyptic setting.
Not for you if you need polished UI and reliable pawn AI — reviews describe clunky menus, workers getting stuck, and rough combat behavior.

City BuilderPost-apocalypticSurvival
$29.99 ~36.4 hr median no co-op complexity: light 70.8% of 5k
The Squirrel's verdictSurviving the Aftermath shifts the focus from individual pawn control to camp-level event and resource decisions, with story-guided progression and expedition mechanics. Reviewers note the systems stop deepening after the first few hours, and several flag that meaningful features are locked behind paid DLC. It holds a Mostly Positive rating at 70.8% positive, with a median of 36.4 hours played.
Not for you if you want granular per-pawn micromanagement, vertical base defense, or a base game that doesn't gate core content behind DLC.
