Strong Mods Strong ModsA deep, active modding scene extends it past its base content.
$9.99 ~28.6 hr median no co-op complexity: light 94.5% of 5k
The Squirrel's verdictTheoTown is a retro pixel-art city builder that originated on mobile and carries that origin in its UI and structure. Community-made plugins serve the role that mods fill elsewhere, with reviewers citing a large and active plugin library. One flat $9.99 price covers the full game across PC, Mac, and Linux, with no expansion DLC. Median playtime is 28.6 hours. Some features, including online regions, are gated behind a daily login currency.
Not for you if you want deep systemic simulation and 3D visuals, or you find mobile-derived interfaces frustrating on PC.

$19.99 ~33.7 hr median no co-op complexity: moderate 82.2% of 10k
The Squirrel's verdictSimCity 4 Deluxe Edition remains, for many reviewers, the deepest city-building simulation available, with a modding community that has sustained it for over two decades. It requires third-party patches and community mods to run stably on modern hardware — that dependency is a barrier, but it also means a vast, mature library of content exists. Median playtime runs 33.7 hours. PC and Mac only, no console version.
Not for you if you want a game that runs without manual patching and mod installation before your first session.

City BuilderFuturisticSci-fi
$17.99 ~51.1 hr median no co-op complexity: moderate 87.3% of 4k
The Squirrel's verdictCliff Empire keeps the resource-chain city building and the satisfaction of watching a settlement grow from nothing, but trades Skylines' open sandbox for a scripted, plot-driven scenario with defined goals. Each cliff runs as its own isolated economy requiring trade between cities. One flat $17.99 price, no DLC layering. Median playtime sits around 51 hours.
Not for you if you want an open-ended sandbox rather than a goal-driven scenario, and dislike managing isolated city economies that must trade with each other to survive.

City BuilderColony SimImmersive Sim
$29.99 ~22.1 hr median no co-op complexity: moderate 77.5% of 1k
The Squirrel's verdictHighrise City keeps the zone-and-grow city building loop but shifts the core challenge from traffic optimization to supply chain management: resources, production chains, and satisfaction math drive growth instead of road networks. Priced at $29.99 with no co-op, it suits players who want Cities: Skylines' scale with an Anno-style economic layer replacing DLC-driven feature creep.
Not for you if you came for traffic engineering rather than resource logistics, or you need a stable build — crashes and performance drops are frequently reported.
5
City BuilderEconomyPolitical Sim
$24.99 ~18.2 hr median no co-op complexity: moderate 73.6% of 1k
The Squirrel's verdictCitystate II puts macroeconomics at the center of city management: immigration rates, inflation, public debt, and policy sliders drive outcomes more than road layout or pipe placement. Reviewers note that zoning and utilities exist but are not the focus. The simulation carries an explicit political framing that some reviewers found limiting. Crashes occur and the game lacks autosave by default, which reviewers flag as a significant issue.
Not for you if you want detailed traffic and infrastructure design, or need reliable autosave — crashes can erase substantial unsaved progress.
6
Colony SimCity BuilderMedieval
$19.99 ~6.9 hr median no co-op complexity: light 70.8% of 1k
The Squirrel's verdictTownsmen shares the core loop of growing a settlement from a small foothold into a working town, with resource chains and citizen needs replacing Skylines' traffic and zoning puzzles. Maps are small, populations run in the hundreds not thousands, and menus surface DLC prompts during building. Median playtime sits at 6.9 hours, suited to short sessions rather than sprawling metropolises.
Not for you if you want a large-scale city sim with thousands of inhabitants rather than a small-map town builder with visible DLC upsells in the build menu.
7
City BuilderEconomyResource Management
$1.49 ~12.3 hr median no co-op complexity: moderate 58.5% of 2k
The Squirrel's verdictCities XL Platinum's defining feature is its inter-city trade and specialization economy: you can build multiple cities on large maps and have them exchange resources, creating regional interdependence most city builders skip. The tradeoff is hard optimization failure — reviewers consistently report that cities lag severely past five or six hours of growth, with no patches issued. Priced at $1.49.
Not for you if you plan to grow a city past early stages, since performance degrades badly and no fixes have been issued.

City BuilderDesign & IllustrationLife Sim
$9.99 ~25.9 hr median no co-op complexity: moderate 57.7% of 477
The Squirrel's verdictSame city-growth loop, small town to metropolis, with huge maps and no agent limit, plus deep budget and growth data Skylines doesn't surface. NewCity strips out utilities and service micromanagement Skylines is built around, focusing instead on economic layers. Reviews report crashes, lag, and RAM strain; Steam rating sits at Mixed.
Not for you if you came to Skylines for granular utility and service systems, or you need a stable, polished build rather than one with reported crashes and performance issues.
