$25.99 ~43.2 hr median no co-op complexity: moderate 84.2% of 89k
The Squirrel's verdictSolo medieval city-builders who want population logistics, food chains, and organic layout design will find Manor Lords a stronger match for those instincts than MMORPG Tycoon 2. It has no co-op, no mod support, and no multiplayer layer of any kind. Reviews note that two years post-release content additions have been sparse, with patches focusing mainly on rebalancing rather than new systems. Median playtime is 43.2 hours.
Not for you if you want co-op, mod support, or steady content additions — reviews consistently describe long gaps between meaningful updates.

Free ~143.1 hr median co-op complexity: moderate 78.2% of 178k
The Squirrel's verdictOnce Human is a free persistent-world survival looter-shooter with co-op, base-building, and a 143-hour median playtime. It shares MMORPG Tycoon 2's persistent multiplayer world and community-building aspect but centers the experience on combat and survival rather than designing and managing a world for others. Reviewers flag recurring monetization changes and patches that have significantly altered systems over time.
Not for you if you want to design and manage a world rather than survive and loot inside one, or dislike monetization systems that change with updates.

Colony SimCraftingBase-Building
$14.99 ~32.9 hr median no co-op complexity: moderate 79.8% of 425
The Squirrel's verdictGrim Realms suits players drawn to colony sims in the Dwarf Fortress and RimWorld tradition: nothing is explained, and jobs like cooking or hauling only function when supply chains, quantities, and placement are configured correctly. Single-player only. Reviews confirm real bugs and a hard performance drop as colonies scale, and it was released labeled 1.0 despite reviewers flagging it as unfinished.
Not for you if you need in-game guidance on how mechanics work, or require stable performance as your colony grows large.

Alek - The Lost Kingdom
PC
AdventureRPGFantasy
$19.99 ~11.2 hr median no co-op complexity: light 77.7% of 413
The Squirrel's verdictPlayers who want to manage villagers, set taxes, patrol territory, and defend a growing settlement will find familiar ground here. Alek is single-player only, with no server or warp logistics; the friction comes from building and provisioning rather than player management. Content runs out between 4 and 11 hours for most players, making it a lighter loop than a deep sim.
Not for you if you want persistent multiplayer world-building or a content loop that extends well past a dozen hours.

City BuilderCraftingMedieval
$24.99 ~21.1 hr median no co-op complexity: moderate 66.3% of 419
The Squirrel's verdictBoth let you build freely with a character-in-world perspective rather than pure top-down management. Empires and Tribes trades MMORPG Tycoon 2's server/inn logistics for medieval city and castle construction with high placement freedom, no wizards or dragons. Reviews report frequent crashes and save-related bugs. For builders who want single-player depth over multiplayer systems.
Not for you if you need stability over freedom, since reviews describe frequent crashes, save bugs, and wayfinding issues that persist across sessions.

Colony SimBase-BuildingOpen World
$24.99 ~14 hr median no co-op complexity: heavy 59.6% of 413
The Squirrel's verdictBoth let you build a society from scratch and watch inhabitants live out generations, but TFM drops the multiplayer/warp-server layer entirely for single-player colony sim with tactical combat and semi-random trait-based progression instead of a tech tree. Good fit if you liked shaping a world more than managing other players' residency numbers.
Not for you if you need a clear tutorial or intuitive UI, since reviews consistently flag the interface as confusing and the learning curve as steep.

City BuilderCombatAdventure
$24.99 ~5.1 hr median co-op complexity: light 58.2% of 297
The Squirrel's verdictBoth share creative base-building as the core loop, with player-driven world construction taking priority over combat or scripted content. Overthrown adds co-op, letting friends build together instead of solo island management. But reviews describe a thin core gameplay loop and lacking base-building depth, and median playtime sits at 5.1 hours, well short of a deep sim.
Not for you if you want deep base-building systems rather than a short co-op session with a bare-bones core loop.

City BuilderColony SimAction RPG
~2.4 hr median no co-op complexity: light 56.3% of 254
The Squirrel's verdictKingdom Builders centers on a single outcast prince building one city, with resource storage caps and population growth as the main constraints. Development has been permanently discontinued and the community Discord shut down, so the game exists only in its current unfinished state. Most players reach the content ceiling within 2.4 hours.
Not for you if you want a city-builder with ongoing development or enough depth to hold attention past two or three hours.
