Cities Skylines 1 vs 2 — Which Should You Play in 2026?
Cities Skylines 1 vs 2 compared: graphics, simulation depth, mods, DLC, performance, and price — and the honest verdict on whether CS2 is worth it in 2026.
Cities Skylines 1 vs 2 — Which Should You Play in 2026?
The short version: CS2 is the better game — better simulation, better graphics, better traffic AI, and it's now in a good state after its rough 2023 launch (performance patches + content updates). But CS1 has the mod library — thousands of Workshop mods that CS2's mod scene hasn't matched yet. Verdict: buy CS2 if you want the modern experience; buy CS1 if you want the mod ecosystem (or a cheap entry).
This guide gives you the honest comparison.
The Comparison
| Cities Skylines (2015) | Cities Skylines 2 (2023) | |
|---|---|---|
| Price | ~$30 (often 75% off sales) | $34.99-49.99 (sale-eligible) |
| Simulation | Good (older sim) | Much deeper (economy, seasons, individual cims) |
| Graphics | Last-gen (moddable) | Modern (weather, lighting, seasons) |
| Traffic AI | Modded into submission (TM:PE) | Better native AI (still imperfect) |
| Mods | Massive Workshop library | Growing (Paradox Mods + community) |
| Performance | Runs on old PCs | Demanding (GPU/CPU heavy) |
| DLC | Huge catalog | Growing |
| Verdict | The mod masterpiece | The modern foundation |
CS2 is the better game out of the box; CS1 is the better game with a thousand mods. Choose based on whether mods or modern simulation matter more to you.
Is CS2 Worth It Now? (The 2026 Reality)
- At launch (Oct 2023): CS2 shipped with performance problems and missing features — it got hammered in reviews.
- Now (2026): Multiple patches + content updates have fixed most launch complaints; the sim depth is genuinely the best in the genre, and the mod platform is maturing. It's worth it now — the launch-era negativity is outdated.
- The honest caveats: It's still heavier than CS1 (needs a decent GPU/CPU), and the mod library is nowhere near CS1's depth.
When CS1 Still Makes Sense
- The mod library: CS1's Workshop has thousands of assets — realistic roads, real buildings, TM:PE traffic tools. If you want "the fully-modded city-builder," CS1 is still unmatched.
- The price: CS1 + DLC is often ~90% off in sales — the budget path.
- Old hardware: CS1 runs anywhere; CS2 needs a modern machine.
