Games like Starship Theory

The Squirrel's verdictCrew survival on a planetary colony rather than a ship interior is the key shift here: hunger, fatigue, and resource gathering all carry over from Starship Theory's loop, but The Pioneers removes automation entirely. Every colonist action requires direct manual input. Reviewers report pathfinding and climbing bugs that can strand crew with no resolution. Median playtime is 10.0 hours.

Not for you if you relied on automation systems, or need stable pathfinding — reviewers report crew getting permanently stuck in climbing or roof-geometry bugs.

The Squirrel's verdictA cloning-labor mechanic defines Surviving the Abyss's colony loop: you generate short-lived clones to staff underwater facilities, which gives the resource chain a different texture than Starship Theory's ship-systems focus. Reviewers flag brutal balance where a misstep around day 90-100 ends a run with no recovery path. Median playtime is 16.0 hours; priced at $19.99.

Not for you if you want difficulty that allows course-correction rather than a single early mistake producing an unwinnable run.

The Squirrel's verdictBoth put you managing a space station's colonists through resource chains, room-building, and crew survival rather than direct control. Starmancer leans harder into colonist AI and station-defense events, with a claustrophobic single-station scope instead of ship design. Steam sits at Mixed, and reviewers report bugs including corrupted saves and disappearing items.

Not for you if you want stable saves and a bug-light experience, since reviewers cite crashes, corrupted saves, and broken tutorial contracts.

The Squirrel's verdictJUNKPUNK adds co-op and a salvage-scavenging theme to the automation-driven base-building loop Starship Theory players recognize. Controls draw consistent criticism from reviewers, who flag awkward camera and movement systems as the main friction point. Steam rating is Mixed at 62.3% positive; median playtime is 22.9 hours at $15.99.

Not for you if you need tight controls, since reviewers consistently report awkward camera and movement systems as a core problem.

The Squirrel's verdictJumplight Odyssey shares Starship Theory's single-ship crew micromanagement and systems-under-strain structure, adding a Battlestar Galactica-style narrative and anime aesthetic. The studio cancelled development and fired half its team; reviewers note the game is technically playable end to end. Median playtime is 12.8 hours at $29.99, with a review posted 14 days ago.

Not for you if you want ongoing patches or a complete feature set, since the studio has publicly cancelled development mid-project.

The Squirrel's verdictSame solo-dev space sim territory: trading, mining, and combat systems that reward tinkering but never fully cohere into content. Drifter trades Starship Theory's base-building for open-world travel with inertia-based flight, faction-less systems, and a slow mission pace. Median playtime sits at 4.4 hours, so this suits players who want short sessions poking at mechanics, not a long campaign.

Not for you if you want factions, a finished economy loop, or more than a few hours of content before repetition sets in.

The Squirrel's verdictCrew-management and trade-run simulation is Cosmonautica's focus rather than ship design or combat: you staff a vessel with Sims-like NPC crew, run trade routes, and watch the economy ceiling arrive faster than most players expect. Reviewers note the developer moved to a new project and stopped patching this one, leaving bugs and a static market economy intact. Priced at $9.99 with a 12.8-hour median playtime.

Not for you if you want an active economy loop, combat depth, or any expectation of future patches.

The Squirrel's verdictSirius shares Starship Theory's solo-developer scope and shaky development history: a small space game built by one person, with reviewers reporting long silences and uncertain progress. Where Starship Theory is closed-system ship management and survival, Sirius is open-space flight and combat in a Freelancer-style setting. Median playtime is 3.6 hours, rated Mixed overall.

Not for you if you expect active updates, multiplayer, or substantial playtime — no co-op, a 3.6-hour median, and no review in over two years.
