Games Like RimWorld: Best Colony Sim Alternatives

RimWorld fans usually want three things: tight colony management, meaningful crises, and stories that practically write themselves. The good news is there are plenty of colony sims that hit the same nerve in different ways. Here are 10 strong alternatives, each with a clear reason to play.

Quick take

• Want maximum emergent chaos? Pick Dwarf Fortress or Oxygen Not Included.
• Want a cleaner, more “city-builder” survival loop? Go with Banished or Farthest Frontier.
• Want systems-heavy sci-fi pressure? Choose IXION or Surviving Mars.
• Want character-driven management with strong “people problems”? Try Prison Architect.
• Want automation-first colony building? Autonauts and Desynced are your best bets.

The 10 picks

Dwarf Fortress

If you play RimWorld for unpredictable stories, this is the deep end. The simulation is absurdly detailed, and tiny choices can spiral into legendary disasters.

What you’ll like:

• Massive emergent narrative potential from world-gen to individual quirks.
• Complex production chains and logistics that reward planning.
• “Losing is fun” energy, but with more simulation and less readability.

Best for: players who want the richest simulation possible and don’t mind a learning curve.

Oxygen Not Included

This is colony survival as an engineering problem. You’re managing heat, gas flow, power grids, and duplicant needs in a closed system that will punish sloppy design.

What you’ll like:

• Systems that interact in satisfying (and dangerous) ways.
• A constant mid-game puzzle: stabilize, optimize, expand.
• Strong “I fixed it” moments when your base stops trying to kill everyone.

Best for: builders who enjoy problem-solving more than combat.

Banished

A classic “small decisions, big consequences” survival builder. It’s calmer than RimWorld, but the pressure is real when winter hits and your supply chain is shaky.

What you’ll like:

• Clean, focused economy and population management.
• Clear feedback loops: food, warmth, labor, tools.
• Great for learning disciplined planning without too many extra mechanics.

Best for: players who want a pure, readable colony survival loop.

Going Medieval

RimWorld-style colony management, but in 3D with vertical building that matters. Defense design, room layout, and production flow feel tactile and strategic.

What you’ll like:

• Layered construction that makes base design more interesting.
• Colonist management with skills, moods, and workloads.
• Raids and threats that reward smart fortification.

Best for: players who love base design and want more spatial depth.

Farthest Frontier

A modern survival city-builder with strong production chains and real scarcity. It delivers that RimWorld feeling of “we’re okay… until we aren’t” through economy pressure and raids.

What you’ll like:

• Detailed industry progression without being overwhelming.
• Meaningful terrain and resource constraints.
• A strong sense of growth from camp to town to settlement.

Best for: players who want a grounded, economy-forward colony sim.

Prison Architect

It’s not a colony in the traditional sense, but it nails management, emergent incidents, and human unpredictability. You’re building a functioning institution while preventing it from collapsing.

What you’ll like:

• Loads of “systems collide” moments: security, needs, schedules, contraband.
• Constant triage between expansion and stability.
• Clear, practical building tools with lots of room for optimization.

Best for: players who like managing people problems more than wilderness survival.

Surviving Mars

A strong sci-fi colony builder with meaningful early survival pressure and long-term planning. Power, oxygen, water, and dome design keep you honest.

What you’ll like:

• Great pacing: fragile startup into stable expansion.
• Distinct sponsors/commanders that shift your priorities.
• Satisfying infrastructure planning across a hostile map.

Best for: players who want a structured colony sim with a clean UI and strong theme.

IXION

This one is pure crisis management in space. You’re running a drifting station, making hard calls, and holding the line while everything breaks.

What you’ll like:

• High tension and constant resource pressure.
• Sector-based station management with consequential upgrades.
• A strong “survive the next problem” rhythm that feels like RimWorld events.

Best for: players who enjoy tough decisions and controlled chaos.

Endzone - A World Apart

Post-apocalyptic colony survival where the environment is the villain. You’ll juggle droughts, radiation, and supply chain fragility while trying to grow.

What you’ll like:

• Frequent external threats that force adaptation.
• Solid settlement progression and logistics management.
• A clear survival focus without getting overly complex.

Best for: players who want survival pressure and rebuilding themes.

Autonauts

This is colony building through automation. Instead of micromanaging colonists, you program bots to do the work, then scale the system.

What you’ll like:

• Automation that’s accessible but surprisingly deep.
• Strong satisfaction from turning manual labor into efficient routines.
• A different kind of story: the story of your system improving.

Best for: players who love optimizing workflows and reducing micromanagement.

Who should play this

• You like colonies that produce stories through systems, not scripted quests.
• You enjoy balancing needs, production, and layout under pressure.
• You want a game where mistakes create new problems, not instant failure.
• You prefer long runs with mid-game complexity and late-game scaling.

Common mistakes

• Picking the “deepest” game first. Fix: start with Banished or Surviving Mars, then move to Dwarf Fortress or Oxygen Not Included.
• Overexpanding before stabilizing essentials. Fix: lock in food/power/storage redundancy, then grow population.
• Ignoring logistics and travel time. Fix: cluster production, use dedicated storage, and reduce hauling distances.
• Designing defenses last. Fix: plan choke points and fallback areas early, even in builder-leaning games.
• Micromanaging everything. Fix: use policies, schedules, automation, or role specialization to keep runs sustainable.

FAQ

Q: Which pick is closest to RimWorld’s emergent storytelling?
A: Dwarf Fortress is the strongest for unpredictable narratives driven by simulation.

Q: Which game is best if I like optimization and base engineering?
A: Oxygen Not Included is the best fit for engineering-focused colony design.

Q: Which one is easiest to get into?
A: Banished has a clean learning curve and teaches core survival planning fast.

Q: Which pick has the most constant “crisis mode” pressure?
A: IXION keeps the tension high and punishes weak planning.

Q: I want less micromanagement. What should I play?
A: Autonauts shifts the workload into automation so the colony runs itself over time.

A comfortable mouse pick for colony sims

If you spend a lot of time in colony sims, a comfortable mouse matters more than you'd think. This pick works well for long sessions with lots of panning, zooming, and menu-heavy play.

Takeaway

If you want RimWorld-style drama, go Dwarf Fortress or Prison Architect. If you want survival with strong structure, pick Surviving Mars or Farthest Frontier. For pure systems and problem-solving, Oxygen Not Included is the safest bet.
