$25.99 ~43.2 hr median no co-op complexity: moderate 84.2% of 89k
The Squirrel's verdictManor Lords trades Becastled's castle-siege defense loop for deep economic simulation: managing crops, trade, and town growth across full seasonal cycles. Reviewers note the castle and combat mechanics remain thin despite the setting. Median playtime reaches 43.2 hours compared to Becastled's quicker mastery curve. Released 2024, $25.99, no co-op, Steam rating Very Positive at 84.2%.
Not for you if you want the castle combat and siege-defense focus of Becastled — castle and combat mechanics are widely described as underdeveloped.

RTSSurvival HorrorBase-Building
$4.49 ~4.7 hr median no co-op complexity: moderate 74.6% of 409
The Squirrel's verdictBlack Forest suits players who want tighter, scenario-based survival goals: some runs have a defined time to survive, which gives more structure than Becastled's open-ended rounds. It leans harder into resource scarcity and difficulty, with repair costs outpacing build speed and combat units described as largely ineffective. Released 2023, $4.49, no co-op, median playtime 4.7 hours.
Not for you if you want combat units that can meaningfully fight back rather than structures you're constantly repairing or losing.

City BuilderCraftingMedieval
$24.99 ~21.1 hr median no co-op complexity: moderate 66.3% of 419
The Squirrel's verdictEmpires and Tribes replaces Becastled's timed siege rounds with open-ended medieval city construction controlled through a walkable character, with no combat timer forcing decisions. Freedom to build almost anywhere is a noted strength, but crashes and save-related bugs are recurring complaints. Steam rating sits at Mixed, 66.3% positive; median playtime 21.1 hours, $24.99, no co-op.
Not for you if you want structured survival rounds rather than open-ended building, or can't tolerate reported crashes and save bugs.

FantasyCraftingMagic
$24.99 ~9.9 hr median no co-op complexity: moderate 66.5% of 212
The Squirrel's verdictBeneath the Mountain runs the same build-manage-survive formula but shifts the setting underground to a dwarf colony, adding rune abilities and trap placement on top of the RTS-survival structure. Reviewers note strong unit variety and enemy diversity. No tutorial is included, and unit pathing issues are a recurring complaint. Released 2024, $24.99, no co-op, median playtime 9.9 hours.
Not for you if you want a tutorial, adjustable game speed, or steady difficulty rather than waves that escalate quickly with no way to slow the pace.

AdventureMedievalDwarf
$9.99 ~5.5 hr median no co-op complexity: moderate 62.2% of 555
The Squirrel's verdictLife is Hard is a 2D tribal town-builder with the same core loop as Becastled: manage resources, construct buildings, and survive escalating threats round to round. It adds a deity-selection system that grants passive bonuses, giving more build variety than Becastled's fixed tech tree. Released 2021, $9.99, no co-op, median playtime 5.5 hours.
Not for you if you need a responsive interface, since reviews describe the UI as unintuitive and sometimes unresponsive, and the Steam rating sits at Mixed.

Base-BuildingPost-apocalypticSurvival
$19.99 ~16.1 hr median no co-op complexity: moderate 60.6% of 2k
The Squirrel's verdictPlayers who like defense-building depth over combat polish will find The Last Haven familiar territory: resource gathering, research, troop management, and wave defense are all present. The setting shifts from medieval castle-siege to zombie and marauder apocalypse, with point-and-click combat and territorial expansion layered on. Released 2023, $19.99, no co-op, median playtime 16.1 hours.
Not for you if you need reliable unit shooting accuracy and consistent enemy AI rather than the combat and mechanic issues reviewers repeatedly flag.

Thrive: Heavy Lies The Crown
PC
RTSColony SimGrand Strategy
$27.99 ~9.5 hr median co-op complexity: moderate 59.2% of 448
The Squirrel's verdictBoth are building-and-survival games where units act on their own and bugs get named specifically by reviewers. Thrive adds story-driven decisions, trade routes, and co-op, plus far more busy work and micro-management than Becastled's simpler survival loop. For players who want depth and don't mind unit pathing issues and slow pacing.
Not for you if you want fast, low-micro sessions rather than heavy resource-chain management and units getting stuck for hours at a time.

City BuilderCombatAdventure
$24.99 ~5.1 hr median co-op complexity: light 58.2% of 297
The Squirrel's verdictOverthrown adds co-op and open-world traversal to the base-building-under-pressure loop, which suits players who want company while building. Reviews describe fun core mechanics undercut by thin content once novelty fades. Released in 2026 as a 1.0 title with a Mixed Steam rating of 58.2% positive, median playtime 5.1 hours.
Not for you if you want a content-complete, polished release — reviewers widely describe it as unfinished despite the 1.0 label.
