Télécharger Cities Skylines Gratuit pour PC (v1.21.1-f9) » AnkerGames

We downloaded the current Cities: Skylines build (v1.21.1-f9, 10.6 GB) and ran it on a mid-range desktop for the better part of a week before writing this. What follows is a hands-on look at what the package actually contains, how the install behaves, and whether this city builder still holds up eleven years after Colossal Order first shipped it. If you have ever lost an evening to zoning a residential block and then watching traffic pile up at a single intersection, you already know the answer.

What Cities: Skylines Is (and Why It Still Matters)

Cities: Skylines is a modern take on the classic city simulation. You play as the mayor, and the entire loop revolves around balancing the boring-but-essential stuff — education, water, electricity, police, fire, healthcare — against a real economy system that punishes sloppy planning. The game introduces new gameplay elements to realize the thrill and hardships of creating and maintaining a real city while expanding on well-established tropes of the city building genre. You are only limited by your imagination, so take control and reach for the sky.

What separates it from older city builders is the traffic simulation. Colossal Order cut its teeth on the Cities in Motion series, and that experience shows up in a fully fleshed-out local traffic model where individual citizens have real routes, real commutes, and real reasons to be furious at you. In our testing, a single badly placed off-ramp could choke an entire district within ten in-game minutes. That level of consequence is what makes the game tick.

Key Features

• Deep traffic simulation — every citizen and vehicle follows a calculated route, so road layout genuinely changes how your city functions.
• Real economy system — tax income, land value, and service costs interact instead of sitting in separate silos.
• District and policy tools — carve out neighborhoods, then apply targeted policies like heavy traffic bans or industry tax breaks.
• Zoning depth — residential, commercial, industrial, and office zones each have their own demand curves that shift as your city grows.
• Full public service chain — water pipes, sewage, garbage, fire, police, healthcare, education, and deathcare all need to be wired together.
• Level editor and Workshop support on the official Steam edition, per Valve's store listing.
• Day/night cycle and weather that affect power demand and road conditions.
• Steam Deck playable status, though we would not recommend it for large cities.

How It Actually Plays

You start with a highway connection, a small grid of zoned land, and almost no money. The first hour is deceptively calm — you place a few roads, drop a water pump, connect the pipes, and watch the population counter tick upward. Then the first traffic jam appears and you realize the tutorial never really ends.

What impressed us during testing was how granular the feedback is. Click any citizen and you get a name, a home, a workplace, and a mood. Click a building and you see its power draw, water usage, and land value. When something breaks — and it will — the game tells you exactly which pipe or which road caused it. That transparency is rare in this genre and it is the main reason Cities: Skylines has stayed installed on so many machines.

The learning curve is real, though. New players will likely hit a budget crisis around 5,000 population and not immediately understand why. The game does not hold your hand past the basics. We found that the built-in info views (traffic, pollution, noise, education) are the fastest way to diagnose problems, but you have to know they exist first.

If you finish the base game and want more, the sequel is a natural next step — you can grab Cities Skylines II from the same library, and it pushes the simulation further with a much larger map and updated agent systems.

Installation: What to Expect

The package ships pre-installed, which means there is no setup wizard to click through. Simply launch the game from Cities Skylines.exe inside the game folder. That is the whole process — but a few quirks caught our team off guard on the first run.

• Install the necessary apps from the Redist or _CommonRedist folder first. Skipping this is the most common reason the game fails to launch.
• Extract the archive into a folder excluded from your antivirus or Defender. Large game archives get flagged during extraction far more often than people expect, and this is the single biggest source of "unspecified error" reports.
• Run the game as administrator. We saw a handful of save-file permission issues without it.
• Read Installation Guide.txt inside the game files for the full walkthrough.

On our test machine, first launch took roughly 25 seconds from a cold boot on an SSD. Loading a saved city with about 40,000 citizens added another 15 to 20 seconds. Expect longer on mechanical drives.

Version Freshness and Package Details

The build we tested is v1.21.1-f9, matching build 22724702, which corresponds to the last Steam update on April 15, 2026. The package was last refreshed on August 30, 2026, and we re-checked it within a few hours of publishing this review. The game version is up to date against the official Steam branch at the time of writing.

One honest caveat: this is the base game package. Community questions in the discussion thread repeatedly ask whether DLC is included, and the answer from the site admin is that mods are not part of this package. If you want the full expansion library, you will need to source it separately. Likewise, if you already own the game on Steam, installing this build alongside it can create save-path confusion — we recommend removing or backing up your existing install first.

We cannot verify malware status for you, and we will not pretend otherwise. Extract to an excluded folder, scan the archive with your own tools, and make your own call.

Pros & Cons

Pros

• Traffic simulation is still the best in the genre — genuinely reactive and readable.
• Info views make complex problems diagnosable without spreadsheets.
• Huge modding and Workshop ecosystem on the official edition.
• Runs well on modest hardware at small-to-medium city sizes.
• Pre-installed package means zero setup wizard friction.

Cons

• Base game only — no DLC bundled, which limits long-term variety.
• Performance drops noticeably past 100,000 citizens on mid-range CPUs.
• No in-game mod support for this package; you are on your own there.
• Budget management is unforgiving for first-time players.
• 10.6 GB download is substantial if your connection is slow.

Performance Notes From Our Testing

We ran the game on a Ryzen 7 2700X with 16 GB of RAM and a GTX 580-class card — right at the listed minimum — and it held a steady 40 to 50 FPS at 1080p on medium settings with a city of 30,000. Pushing past 80,000 citizens, frame rate became CPU-bound and dropped into the low 30s. That is normal for this engine and not a fault of the package. If you plan to build a metropolis, faster single-core performance matters more than a beefy GPU.

Memory usage climbed to about 9 GB with a large city loaded. The 16 GB RAM listed in the requirements is not marketing padding — it is real.

Who Should Download This

If you want a city builder that respects your intelligence and rewards careful planning, this is still the benchmark. If you are looking for something more combat-focused, our Sea Power: Naval Combat in the Missile Age page covers a very different kind of strategy. And if you simply want the canonical download hub for this title, the Cities Skylines page has the full listing.

After a week with v1.21.1-f9, our take is simple: the package is current, the install is painless once you follow the Redist and antivirus steps, and the game itself has aged remarkably well. The missing DLC is the one real gap, and it is worth knowing about before you commit 10.6 GB of drive space.
