The Squirrel's verdictCities: Skylines suits players who want a modern city-building simulation that runs natively on current hardware without third-party patches. Traffic-agent simulation and a large modding community are its main strengths. The base game is deliberately limited, and reviewers cite roughly $120 of DLC to reach a full-featured experience, plus mods that can break after updates. Steam rating is Very Positive at 92.9%, with a median 69.3 hours played.
Not for you if you want a complete out-of-the-box experience without layering mods and substantial DLC spending.

The Squirrel's verdictTheoTown is a pixel-art city builder with zoning, region play, and an active plugin community, all at $9.99. Its simulation is deliberately lightweight — power, traffic, and economic interdependencies are simpler than SC4's. Beginner-friendly UI and no paid DLC are consistent positives in reviews. Median playtime is 28.6 hours. Region hosting online requires a daily-login currency, which some reviewers flag as a significant friction point.
Not for you if you want deep interlocking simulation systems or find mobile-derived UI conventions and gated online features frustrating.

$29.99 ~22.1 hr median no co-op complexity: moderate 77.5% of 1k
The Squirrel's verdictHighrise City shares zoning and city-scale building with SC4 but shifts the core loop to production chains: resources feed manufacturing, manufacturing feeds amenities, and housing stalls without both. It's closer to Anno than SC4's traffic-and-budget management. For players who liked SC4's systems depth but want supply-chain logistics instead of road optimization.
Not for you if you want SC4's traffic and budget focus rather than tracking resource and production chains, or crashes and frequent freezes will break your session.

The Squirrel's verdictPlayers wanting a large-scale 3D city builder with modern traffic simulation and current hardware support will find Cities: Skylines II the closest structural successor to SC4's zone-and-grow format. Reviews note meaningful stability and performance improvements under Iceflake Studios, though simulation bugs remain. Steam rating is Mixed at 55.1% positive. Median playtime is 60.4 hours. Priced at $49.99.
Not for you if you need a fully stable simulation free of reported bugs and save issues before investing significant time.

City BuilderEconomyPolitical Sim
$24.99 ~18.2 hr median no co-op complexity: moderate 73.6% of 1k
The Squirrel's verdictBoth are single-city builders driven by zoning and RCI demand, but Citystate II shifts weight from traffic and infrastructure design toward macroeconomics and politics: immigration rates, inflation, public debt, policy sliders. Good fit for SimCity 4 players who want the simulation layer deeper than the road-building layer, not prettier interchanges.
Not for you if you came to SimCity 4 for road and infrastructure design, since Citystate II treats those as secondary to slider-driven economic and political systems, and it lacks co-op.

$1.49 ~12.3 hr median no co-op complexity: moderate 58.5% of 2k
The Squirrel's verdictCities XL Platinum shares the single-city, zone-and-build core and inter-city trade adds a layer SC4 never had. Graphics and UI are more modern and easier to pick up, but the simulation is shallower and less demanding than SC4's economy. Large maps let cities grow bigger before things bog down, mechanically and technically.
Not for you if you need SC4's depth of economic simulation, since reviewers describe worsening lag and bugs once cities grow past a few hours.

City BuilderDesign & IllustrationLife Sim
$9.99 ~25.9 hr median no co-op complexity: moderate 57.7% of 477
The Squirrel's verdictNewCity keeps the zoning-and-growth-watching core SC4 players know but strips out utility micromanagement like power, water, and sewage, focusing instead on realistic budget and population data on huge, agent-unlimited maps. Steam rating sits at Mixed, with reviews citing crashes and lag. Median playtime is 25.9 hours, far short of SC4's mod-fed longevity.
Not for you if you want the utility and service management SC4 gives you, or you need a stable build rather than one with reported crashes and lag.

$1.99 ~9.2 hr median no co-op complexity: moderate 40.7% of 2k
The Squirrel's verdictCities XXL shares the single-city zoning and infrastructure-management core with SimCity 4, but reviewers describe it as a barely-updated reskin of the earlier Cities XL, with only two new features and no meaningful engine changes. At $1.99 with a median 9.2 hours played, it's a cheap way to sample city-building mechanics without SimCity 4's mod-driven depth or community.
Not for you if you want the sprawling mod ecosystem and long-term depth SimCity 4 offers rather than a short, largely unchanged reskin of an older title.
