Cities Skylines 1 vs 2 in 2026: simulation, graphics, traffic AI, mods, performance and price — plus which to buy by platform, budget and playstyle.
Cities Skylines 1 vs 2 — Which Should You Play in 2026?
The short version: in 2026 the answer is "it depends on your platform and hardware." If you're a pure PC player with a capable rig: CS2 is worth buying now — the launch performance and content problems were largely fixed through the 2025-2026 patch cycle, and Steam reviews sit at 74% positive over the last 30 days. If you need the vast mod ecosystem or run a low-end PC: CS1 remains unmatched (the Workshop's tens of thousands of mods are something CS2 can't catch up to any time soon). And one big caveat: console players can only play CS1 — the CS2 console version is still indefinitely delayed. If you're searching "cities skylines 1 vs 2," you're making a purchase decision, so this guide does the math per platform.

Core Comparison Table (2026)
| Dimension | Cities: Skylines (2015) | Cities: Skylines II (2023) |
|---|---|---|
| Price | $29.99 (all-time lows at 75% off) | $49.99 (usually 30% off) |
| Simulation depth | Good, but hard-capped (~65k citizens) | Deeper: individual citizens, economy chains, seasons/climate, no population hard cap |
| Graphics | Last-gen (mods to the rescue) | Modern: lighting/weather/seasons |
| Traffic AI | Weak — TM:PE mod required | Better natively (still not perfect) |
| Mods | Massive Steam Workshop library (tens of thousands) | Paradox Mods, maturing by 2026 but far fewer |
| Performance needs | Runs on nearly any 10-year-old PC | High: the official minimum only means "it opens" |
| Platforms | PC/Mac/Linux/PS4/Xbox One/Switch/Remastered | PC (Windows) only; consoles TBA |
| Reception | Overwhelmingly Positive (90%+) | Mixed 57% overall, Mostly Positive 74% recent (30 days) |
Go CS2 if you can — simulation and graphics are better across the board. Stay on CS1 if you live in the mod ecosystem or have an older PC. Console players have no choice: it's CS1.
CS2 in 2026: Is It Worth Buying Now?
- At launch (Oct 2023): performance issues plus missing features; Steam reviews cratered to ~40% and the internet wrote it off.
- Now (Aug 2026): multiple patch cycles fixed most performance issues; content keeps landing (the Bridges & Ports expansion in Oct 2025, ongoing creator packs); Steam is at 74% positive over the last 30 days (Mostly Positive), 57% overall (Mixed) — the reputation is clearly recovering.
- Dev team: handed from Colossal Order to Iceflake Studios in early 2026, update cadence maintained.
- Remaining weaknesses: the mod-count gap vs CS1 is enormous; far more demanding than CS1; the console version is still nowhere.
① Your PC: the official minimum (i7-6700K + GTX 970) only means "it opens" — smooth play wants 16GB RAM and a modern GPU, see the system requirements guide; ② platform: if you only own a PS5/Xbox/Switch, you can't buy CS2 today, see the platforms guide.
Why CS1 Is Still Worth It
- Mod ecosystem: TM:PE (traffic), Move It (fine placement), 81 Tiles (the whole map) — "complete city building" is only available in CS1 right now.
- Price: all-time low around $7; all 11 expansions on sale together is pocket change (expansion rundown in the DLC guide).
- Low-end friendly: it's a 2015 game — any PC from the last decade runs it, big cities included.
- Platform reach: the only option for console players.
Decision Table: Which Should You Buy?
| Your situation | Buy |
|---|---|
| Mid/high-end PC (16GB+ RAM, RTX 3060-class or better) | CS2 (add CS1 on sale later if you like) |
| Low-end PC / laptop | CS1 (CS2 will stutter you out of the hobby) |
| Can't live without mods (TM:PE/Move It/assets) | CS1 |
| Only care about the newest simulation/graphics | CS2 |
| PS5 / Xbox / Switch player | CS1 (CS2 console version not released) |
| Budget-sensitive, want a cheap trial | CS1 (all-time low ~$7) |
| Veteran upgrading | CS2 — the simulation depth is worth it |
CS1 at its all-time low plus CS2 on sale = a complete city-builder double setup. That's actually what most veterans do: CS1 as the mod powerhouse, CS2 as the simulation powerhouse, each covering the other's gaps. Saves and mods do not transfer between the two games.
Frequently Asked Questions
Is Cities Skylines 2 worth it in 2026?
Yes — most launch problems are fixed, recent reviews sit at 74% positive, and its simulation depth leads the genre. If you're price-sensitive, wait for a 30% discount (all-time low around $35).
Is CS1 or CS2 better?
Depends on your priorities: simulation/graphics/modernity → 2; mod ecosystem/low-end hardware → 1. CS2's reputation is clearly rebounding, but its mod pool is still far behind CS1's.

Mid/high-end PC → CS2; low-end/mod-dependents/console → CS1; budget buyers → try CS1 at its all-time low first, then add CS2 if you love it.

Mostly. The 2025-2026 patch cycle and content updates solved most launch problems; performance and mod-ecosystem gaps remain, but the core experience is fine.
Can I use CS1 mods in CS2?
