$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.

MMORPGOpen WorldAdventure
~22.3 hr median no co-op 74.4% of 285
The Squirrel's verdictReign of Darkness puts you inside a persistent multiplayer RPG rather than designing one from the outside: you pick your own spells and passives to build a unique class, then grind with a small online community. The 74.4% Mostly Positive rating and 22.3-hour median playtime reflect a niche that lands well for the right player, though reviews split sharply on developer communication and whether the single dev can sustain the game long-term.
Not for you if you need reliable developer communication, a finished game, or content that extends well beyond the current early state.

SurvivalOpen World Survival CraftCrafting
$14.99 ~18.9 hr median co-op 71.6% of 894
The Squirrel's verdictSolace Crafting is built around a tiering-and-expansion loop: gather, craft, decide how far to build out at each tier before pushing to the next, alone or in co-op. The single-dev origins show in rough controls and animations you learn by trial and error, but the 71.6% Mostly Positive rating and 18.9-hour median playtime suggest the core progression hook holds for players willing to tolerate unpolished edges.
Not for you if you want polished controls and animations rather than a rough, solo-dev system you learn by trial and error.

Magisterium: Fantasy Craft
PC
ActionAdventureRPG
$14.99 ~22.6 hr median co-op 70.5% of 244
The Squirrel's verdictPlaying inside the world rather than designing it is the defining flip here. Magisterium: Fantasy Craft has you hunt, fish, craft, and take quests from villagers as a character with manual saves and EXP loss on death. Co-op is supported. The 70.5% Mostly Positive rating and 22.6-hour median playtime come with caveats: unclear quest directions and combat that reviewers describe as imprecise.
Not for you if you need responsive combat and clear map markers — reviews describe combat as button-mashing and navigation without reliable waypoints.
